In recent years, the EVA pencil case has carved out a firm place in the stationery and promotional product industries. It’s no surprise — the material is lightweight, resilient, and lends itself well to a sleek, modern design. But before jumping into bulk purchasing, buyers in the B2B space would do well to pause and consider a few important aspects. A smart decision at the sourcing stage often sets the tone for everything that follows — from brand perception to end-user satisfaction.   1. Not All EVA Is the Same On paper, EVA (ethylene-vinyl acetate) seems like a straightforward material. But in practice, there are major differences depending on the grade used. The feel, the finish, even the durability of an EVA pencil case can vary quite a bit based on how it’s formulated and processed.   Some suppliers use lower-density EVA that’s more prone to denting or warping over time. Others cut corners on zipper quality or inner mesh linings. That’s why requesting physical samples—or better yet, visiting the production facility if possible—can make all the difference in a long-term partnership.   2. Customization Goes Beyond Just Logos For businesses considering the OEM & ODM EVA pencil case route, customization isn't just about slapping on a logo. You should be thinking in terms of full product identity: the shape of the case, color combinations, zipper styles, interior layouts, and even retail-ready packaging.   A supplier with strong ODM capabilities can help you refine your ideas or offer ready-made solutions based on proven design models. The best partnerships are often collaborative—where your market insights meet the manufacturer’s technical know-how.   3. Timing and Flexibility Matter More Than You Think It’s easy to underestimate lead time—until you miss a back-to-school window or a trade show deadline. Some manufacturers can handle rush orders; others can’t. It’s crucial to establish realistic expectations early on.   Discuss how long it takes to finalize a mold or color sample, and ask what happens if you need to scale your order unexpectedly. For buyers managing seasonal inventory, choosing a supplier that offers production flexibility might matter just as much as price per unit.   4. Compliance Isn’t Optional Markets like the U.S. and EU have strict rules when it comes to children’s products and materials safety. EVA may be non-toxic by nature, but the additives used during manufacturing can sometimes lead to compliance issues.   Ensure your supplier can provide valid certification, such as EN71 or REACH for European markets, or CPSIA testing for U.S. compliance. A good supplier should be proactive in providing this documentation—if they’re hesitant, consider it a red flag.   5. Small Details Leave Big Impressions In the world of retail and branded merchandise, it’s often the little things that count. A pencil case with a sturdy zipper, a well-organized interior, or even just a clean finish can elevate your product from average to premium.   Many suppliers also offer packaging solutions—custom inserts, sleeves, hang tags, or blister packs—that make the product retail-ready straight from the factory. Don’t overlook these touches; they play a key role in how your product is perceived.   Choosing the right EVA pencil case supplier isn’t just about ticking boxes for price and quantity. It’s about finding a manufacturer that understands your brand goals, can work within your timelines, and has the capacity to deliver consistent quality—Yisi Packing has been crafting innovative, custom EVA packaging solutions with a dedicated team of experienced professionals.

When choosing air conditioners, many customers will see a label with a SEER value. While the salesman would stress that the higher the SEER, the more energy-saving the air conditioner will be. But is the higher SEER a better option? Now we are showing you the facts behind it and helping you select the air conditioner more scientifically.   I. What is SEER?   SEER, fully named Seasonal Energy Efficiency Ratio, is used to measure the average energy efficiency level of an air conditioner in one cooling season.        Calculation formula: SEER = Total annual cooling capacity (BTU) ÷ Total annual electricity consumption (Wh).   The higher the SEER value, the better the cooling effect of the air conditioner in the unit power consumption and the better the energy-saving performance.   II. Is a higher SEER necessarily better?   From the perspective of energy saving, it's true that higher SEER saves more electricity, but it depends on several factors: Advantages: Lower electricity cost High-SEER air conditioners will consume less electricity in long periods of operation, making them suitable for regions with high temperatures or long-term usage, such as the Middle East and Southeast Asia.   More Eco-friendly Higher energy efficiency means less emission of carbon, which applies to the policies toward environmental friendliness and energy saving in European and American regions.   Easier to pass export certification CE, GCC, ISO, and other certificates are all included with energy efficiency estimation. Air conditioners with higher SEER will be more likely to pass the tests and acquire the market access. Notes: High SEER ≠ the most energy-efficient in actual use SEER value is tested in standard working conditions, while the actual using environment, installation, and the indoor heat burden will all influence the energy-saving effect.   Higher cost on the air conditioners High-efficiency air conditioners are normally adapted with a full DC inverter system, an excellent compressor, and a high-efficiency heat exchanger, combining to create a higher initial cost. It needs to weight the cycle of investment feedback based on the budget.   High requirements for maintenance High-efficiency systems have high requirements for maintenance, cleaning, and installation, which are necessary to inspect regularly in the long-term use to maintain the working efficiency.   III. How to select a cost-effective air conditioner with high SEER?   Normal household users: We recommend choosing an air conditioner with a SEER between 15 and 18, considering initial cost and energy-saving performance.   Commercial/long-term operation scenarios: Offices, canteens, and breeding farms can choose SEER 20+ air conditioners with low operation costs, which is considerable in long-term energy savings.   Export enterprises/dealers: It is necessary to focus on the local compulsory requirements of energy efficiency if exporting to the Middle East and Europe markets, such as SASO, SEER >= 13, EU ERP standard, etc.     IV. SEER advantages of KRG air conditioning products   As a professional exporting brand in air conditioners, KRG provides a series of products from SEER13 to SEER25+, meeting different energy efficiency demands in various markets: We support several international energy efficiency certifications, such as GCC, ISO, CE, CQC, ROHS, and ect. We provide T1/T3 air conditioner solutions for high-temperature regions. Our products apply to various scenarios: household, commercial building, farming, etc. We can customize high-efficiency air conditioners that meet energy-saving project bidding requirements   It is true that SEER is the key index to weigh the energy-saving performance of air conditioners. Whether the higher SEER product is much better, it needs a comprehensive evaluation based on actual demands, operation environment, and the budget. Only by choosing a proper and suitable SEER value can we achieve energy savings, environmental friendliness, and the maximization of long-term value in a real sense.

How Do Mechanical Thermostats Work? The temperature sensor in a mechanical thermostat (also known as bi-metal) is made up of two pieces of metal that are laminated together. Each type of metal has a different rate of expansion when heated or cooled, which is what controls the thermostat temperature.  Note: Mechanical thermostats operate within a temperature range and you are not setting an actual temperature. The thermostat manufacturer calibrates the thermostats in the test lab, so the numbers on the thermostat closely match the actual temperature of the room. This means the temperature in your room will stay around your set point, but can be about five degrees above or below it at any given time.   How Do Electronic Thermostats Work? Electronic thermostats have digital sensors to read the room temperature. They're much more accurate and responsive than mechanical thermostats, which means your room should stay within 1 degree of the temperature you set on the thermostat.  Note: In addition to increasing comfort, the smaller temperature swings of electronic thermostats can translate to energy savings.    How To Know Which Thermostat To Choose? Even though mechanical thermostats aren't as responsive as electronic thermostats, our Vice President of Engineering says that some people want to use a thermostat like an on and off switch. In this case, mechanical thermostats are an excellent choice because they are more affordable than their electronic counterparts.   Note: Electronic thermostats aren't designed to withstand a certain amount of power or inconsistency. Power surges or "noise" on a power line could potentially fry their electronic components.    If you're still on the fence about choosing either a mechanical or electrical thermostat, check out our blog on controlling a thermostat to know which option is best suited for you.  

When choosing air conditioners, most people are concerned about the brand, efficiency, and horsepower. They often miss a key factor, which is the installation position. In fact, even if you purchased a high-efficiency air conditioner, if the installation position is unconventional, then the cooling performance will be decreased and energy consumption will be high, or the life span will be shortened, etc. So how important is the installation position? How to choose a perfect position for installation? Here we will explain and help you pick out the best position to install your air conditioner.   I. The impact of improper indoor unit location   1. Uneven cooling, bad comfort feeling If the air conditioner is installed on one side or locked by the furniture in the room, the cold air can not be spread evenly. This will easily lead to "one side cold, other side warm" and greatly discount the feeling of comfort.   2. Lower cooling efficiency, more energy consumption The air conditioner starts frequently to adjust the temperature, consuming more electricity and damaging the air compressor easily. It's not cost-effective in the long run.   3. Blow directly toward human body; it triggers "air conditioner illness" Installation at a lower position or facing the bed will make the cold air blow directly on the head or body, easily lead to "air conditioner illnesses" such as cold, headaches, muscle stiffness, etc.   The indoor unit shall be installed in the middle-upper part of the room, avoiding the positions that could blow directly on the human. The air vent is toward the open zone of the space, which is better for cold air to spread.     II. The impact of improper outdoor unit location   1. Bad radiation, lower cooling ability If the outdoor unit is placed under direct sunlight or bad ventilation and the heat can not be radiated effectively, then the cooling efficiency will be greatly decreased.   2. More noise and vibration Installing on window sills, corners, or weak structural areas can cause noise and vibration problems due to resonance or unstable support. If the air conditioner is installed on window sills, corners, or weak structural areas, because of the resonance or unstable support, it will make noise and vibration problems.   3. Lifespan problem Being long-term exposed to sunlight or heavy dust accumulation will accelerate the aging of the outdoor unit, influencing the lifespan of the whole unit.   The outdoor unit should be placed in a cool and ventilated location, such as a balcony, and keep a heat radiation area of at least 30 cm around it.     III. Common misconceptions inventory Misconceptions Description Concern on beauty rather than the air flow. If the air conditioner is installed too high or blocked by the ceiling, cold air circulation is hard to achieve. The outdoor unit is too close to the wall. The space for heat dissipation is not enough, affecting the operation efficiency of the compressor. The indoor unit faces the bed. The cold air blows directly to the human body, influencing our health. The distance between indoor and outdoor units is too long. This will lead to too long a connecting pipe, increasing the energy consumption and installation cost.   IV. Advice for the best installation position.   Bedroom: It should be installed in the upper position of the side wall, avoiding facing the bed. Living room: It's better to choose the position near the center of the ceiling or the unblocked wall. Office: Keep it away from the workplace, ensuring the cold air is dispersed in the activity area. Child's room: Avoid direct blowing and concern yourself with the adjustable wind direction.     V. Reasonable installation consumes half the efforts   Whether your home air conditioner works well or not, the installation position determines. Proper installation can not only improve cooling efficiency and energy-saving effects but also extend the lifespan and secure family health. As for an air conditioner, 30% is based on the quality and 70% is on the installation. Please refer to the professional guidance before installation, or give this job to the servicemen.  

In the $180B global cosmetics market, customizable tubes dominate 67% of skincare packaging.Cosmetic tubes are widely used in cleansers, eye creams, primers, sunscreens and other products due to their lightness, good sealing and portability. This article will give you a comprehensive understanding of tube packaging from three aspects: the manufacturing process of tubes, surface treatment technology and common types of matching caps. Manufacturing Process of Skin Care Tubes Skin care tubes are usually made of PE (polyethylene) plastic, aluminum foil, plastic film and other materials.They are made into sheets by co-extrusion and compounding, and then pressed into tubular containers by a special tube making machine. The production process of tubes mainly includes: extrusion molding → cutting → printing → sealing → capping. Each step needs to be precisely controlled to ensure aesthetics and sealing. According to product type and usage requirements, they can be divided into single-layer tubes, multi-layer co-extrusion tubes and aluminum-plastic composite tubes: Tube Surface Decoration The printing color should be within the specified tube body range, the overprint position should be accurate, the deviation should be within 0.2mm, and the font should be complete and clear. In order to enhance brand recognition and shelf appeal, hoses are often combined with different surface decoration processes. The following are several mainstream technologies: 1. Silk Screen Printing Suitable for small batches and multi-color customization, with thick ink and strong feel. Like the printing method of plastic bottles and glass bottles, color registration is required. 2. Offset Printing High color reproduction, suitable for large-scale printing, mostly used in basic daily chemical lines. Similar to paper printing, large color blocks and multi-color printing are possible. Offset printing is often used for hose surface treatment. Most of the inks used are UV-dried, requiring strong ink adhesion and resistance to discoloration. 3. Hot Stamping Highlight the logo or pattern, enhance the product texture, often used in high-end skin care series. 4. UV Printing/Varnish (UV Coating) Partial high gloss or matte treatment makes the product visually more layered. It can be UV, matte and glossy. Although the matte surface treatment is elegant, it is easy to get dirty and leave fingerprints. 5. Pearl/Gradient Coating (Pearl/Gradient Coating) Create a visually attractive metal or gradient effect to enhance the brand's sense of luxury. Tube Caps Options 1. Flip-top Cap Easy to operate, suitable for daily cleansing and shampooing products. 2. Screw Cap Stronger sealing performance, commonly used in eye cream and sunscreen products. 3. Pump Head Improve the convenience of use, commonly used in hand sanitizer or lotion hoses. 4. Nozzle Tip Precisely control the amount, suitable for segmented care products such as eye cream and acne cream. 5. Metal Roller Ball Add massage function, used for eye care or anti-wrinkle essence hoses. Why choose hose as skin care product packaging? Lightweight and easy to carry: suitable for travel and daily use; durable, recyclable, easy to squeeze; Good sealing: effectively prevents content contamination and oxidation; Strong customization: color, printing and cover type can be flexibly customized; High cost performance: compared with glass bottles and vacuum bottles, it is suitable for low-end and mid-range product launches. Conclusion: Customize your skin care hose packaging Guangzhou Panyue Packing Co., Ltd. : As a professional OEM/ODM supplier of skin care packaging materials, we not only provide a variety of hoses, but also provide one-stop customized solutions with different printing processes and cover types. From proofing to mass production, from design to delivery, we help brands create skin care packaging that is both practical and aesthetic.  

Under the background of global dual carbon goals (carbon peak and carbon neutrality), as well as the related laws becoming more and more strict, the air conditioning industry is accelerating the pace of update and replacement in refrigerant. As the representatives of new refrigerants, R32 and R290 have different environmental specifications and marketing applications. Here we will have a comprehensive introduction to help you make a clear decision.   I. Basic comparison Gas type Chemical name GWP value ODP value Flammability Common applications R32 CH₂F₂ 675 0 A2L Residential/ Commercial use R290 C₃H₈ 3 0 A3 Refrigerator, small air conditioning equipment   II. Comparison of environmental performance   1. GWP value: R290 is more advantageous in "0 carbon dioxide"   GWP (Global Warming Potential) is the key data to measure the air impact on the greenhouse effect. R32 has a GWP of 675, which is less than R410A (GWP-2088), but it still belongs to the GWP middle class. R290 has a GWP of 3, which is almost negligible.   2. ODP value: both have 0 ODP   Both refrigerants have no impact on the ozone layer (ODP=0); they totally meet the requirements of the Montreal Protocol.   III. Energy efficiency and performance   R32 and R290 have outstanding thermodynamic performance, but there are slight difference   Assessment dimensions R32 R290 Cooling ability high higher than R32 Energy efficiency ratio higher (10% better than R410A) more higher (5-10% better than R32) Air compressing efficiency high very high   In a word, R290 is better than R32 in heating exchange ratio and energy efficiency ratio.   IV. Safety and applicable range   1. Clear difference in flammability.   R32: A2L class, a bit flammable, higher safety level. It is suitable for home air conditioner promotion. R290: A3 class, very flammable; it highly requests safety in installation and maintenance. And the risk of fire disaster exists.   2. Legal restrictions and applications   Due to its high flammability, the R290 air conditioner is now limited in applications in global countries, which are only allowed to apply it under certain capacities. (For example, China standards limit the charging weight of 150g, while the Europe is 290g.) In large or enclosed spaces, it is normally prohibited to use R290.     V. Marketing trends and policy orientation   R32 It is widely adapted by international trending brands, such as Daikin, Gree, Midea, Mitsubishi, etc. As a transitional refrigerant with environmental friendliness, it complies with the environmental protection policies in different countries. And the technology is mature, and the supply chain is stable. It is suitable for the exporting of major household and commercial air conditioners.   R290 It is more and more preferred by small cooling devices, such as refrigerators and portable air conditioners. Europe and other regions promote it on a large scale, but it is still limited due to its flammability and charging weight. It requires a higher standard of the manufacturers and service providers on safety design and maintenance capability.   VI. Which one is the most eco-friendly option? Comparison R32 R290 GWP value medium (675) low (3) ODP value 0 0 Energy efficiency performance better much better Safety high (controllable) high flammability with risk Application maturity mature, widely used not so mature, more limitations Cost and supply chain mature and stable low cost, high requirements on storage, transportation and supervision   R32 is the most balanced refrigerant regarding comprehensive performance, environmental friendliness, and safety. It is applicable for many mainstream air conditioners. R290 is more eco-friendly but more flammable, suitable for small, specified-capacity equipment.     Driven by the environmental protection trend and the governmental policy pressure dually, air conditioning refrigerant is now undergoing a green conversion. As the main force of green refrigerants in the current market, R32 is obviously advantageous in controllable cost, security performance, global legacy, etc. While R290 is representing the development direction of "ultimate green refrigerant", which is adaptable for scenarios where the technology maturity is higher and the security system is complete.   If you are looking for international standard R32/R290 air conditioners with high efficiency, please contact us.
