Co-extrudierte POE-Verpackungsfolie, warum wird EPE verwendet?

In solar modules, encapsulation film is an essential component. It is a major determinant of the lifespan and quality of solar module goods. Nowadays, polyolefin elastomer (POE) film and ethylene vinyl acetate (EVA) are the two primary materials utilized in the solar film industry.

POE materials have excellent fluidity and a narrow molecular weight distribution, despite their poor water permeability and high body resistance. After lamination, bubbles are easily produced, and issues with lamination reduce component yields. Simultaneously, the cost is 30% greater than EVA.%~50%, and the multi-busbar double-sided modules’ high film weight need raises the module’s packaging cost.New co-extruded POE materials have been introduced to the market to address this issue.

​Owing to its exceptional flexibility, toughness, and adaptability, co-extruded POE (Polyolefin Elastomer) packaging film is a material that is applied widely in many different industries. The specific use of expanded polyethylene (EPE) in co-extruded POE packaging film is thoroughly examined in this article. It emphasizes the exceptional benefits, special qualities, and contrast with conventional additives when it comes to resolving aging problems in photovoltaic (PV) components.

 

 

Because of its unique properties, EPE is a crucial component of co-extruded POE packaging film. EPE is a low-density, closed-cell, non-crosslinked polyethylene foam with excellent impact resistance and cushioning capabilities. Multiple layers of POE and EPE are simultaneously extruded during the co-extrusion process, producing a film with improved performance and protective qualities.

Enhanced Aging Resistance: When incorporated into co-extruded POE packaging film, EPE considerably increases the aging resistance of PV components. Because of its closed-cell structure, which functions as a barrier, less moisture, UV light, and other environmental elements that can hasten destruction can penetrate. By lowering maintenance costs and lengthening the operational lifespan, this improved protection guarantees the durability and dependability of PV modules.

Excellent Shock Absorption and Cushioning: EPE’s distinct cellular structure offers superior shock absorption and cushioning qualities. It protects delicate products well during storage and transportation when added to co-extruded POE packaging film, reducing the possibility of damage from hits or vibrations. Because EPE can cushion, things arrive safely, increasing customer satisfaction and lowering product returns.

 

 

EPE is a lightweight substance that helps reduce the total weight of the packaging sheet. It is also cost-effective. This feature of lightweight helps lower shipping costs in addition to making handling and transit easier. Furthermore, because it is readily available, simple to process, and recyclable, EPE is an affordable option that is well-liked by a variety of businesses.

Versatile Use: Co-extruded POE packaging film containing EPE is widely used in a variety of sectors. It is frequently used to safeguard breakable items during transportation, including appliances, glassware, electronics, and car parts. In addition, it functions as a moisture barrier, offers cushioning in building and construction applications, and provides insulation for both thermal and acoustic purposes.

 

 

Co-extruded POE packaging film with EPE is becoming increasingly used in sectors like electronics, automotive, e-commerce, and logistics. It protects delicate electronic equipment from shocks and static electricity in the electronics industry. It safeguards automobile parts during assembly and transportation in the automotive industry. EPE’s cushioning qualities help the e-commerce and logistics industries by guaranteeing the safe delivery of fragile goods to clients.

Many sectors benefit greatly from the inclusion of EPE in co-extruded POE packaging film. It is a favored option for packaging applications due to its outstanding age resistance, great cushioning, impact resistance, lightweight design, and affordability. Co-extruded POE packaging film with EPE has a wide range of applications in industries like electronics, automotive, e-commerce, and logistics. This mix of materials lowers expenses, improves customer happiness, and protects the product. Co-extruded POE packaging film’s continued development and use of EPE will spur innovation and meet changing packaging requirements across a range of sectors.
