The machinery is described as flexible, with adjustable die width and film thickness, and capable of customised machine design for targeted output. It is also highlighted for low energy consumption and a cost-effective recycling system.

Material Specifications and Film Properties

The production lines are designed to process EVA resin and can also accept combinations of different resin materials such as LDPE, LLDPE, and HDPE to combine their unique properties. The lines are specially designed for these thermoplastic polymers, with processing requirements for screws, flow channels, and guiding rollers taken into consideration for best quality.

EVA is described as a copolymer of ethylene and vinyl acetate. It is characterised as an extremely elastic and tough thermoplastic with excellent clarity and gloss and little odour. It possesses good flex crack and puncture resistance, is relatively inert, adheres well to many substrates, and is heat sealable. These properties make its use in film applications especially attractive.

For solar panel encapsulation, the film is a new type of thermosetting hot melt film, anti-adhesive at normal temperature, and easy for operation. It becomes fully shaped and adhesive after heating and laminating. It is designed to make silicon wafer, glass, and backplane multi-layer materials firmly bonded into a single unit, offering excellent heat and humidity resistance, UV resistance, and long-term use in outdoor requirements. EVA film for this purpose is noted for environmental protection, long-term UV resistance, no yellowing, high light transmission, strong adhesion, aging resistance, and low thermal shrinkage. Its functions include high light transmittance for cell modules, preventing water vapour penetration, and providing high and low temperature resistance and anti-ultraviolet light properties.

Another material mentioned is POE (polyolefin elastomer), which has the general characteristics of thermoplastic elastomer but also has excellent toughness and good processability.
