The design of composite packaging film

Composite packaging film in order to meet the needs of packaging requirements, should have the following properties: 1, the mechanical properties of tensile strength, rigidity, abrasion resistance, impermeability, elongation friction, etc. 2, physical and chemical performance cut off oxygen and moisture performance, incense resistance, oil resistance, resistance to chemical media, avoid light, etc. 3, durable performance under the environment of low temperature, high temperature performance, under the condition of high temperature stability, interpretation ability and so on. 4, processability, suitable for printing, easy to automatic packaging, antistatic, thermal contraction ability, etc. 5, merchandise display transparency, whiteness, glossiness, opens conveniently, waste easy processing, etc. Such as the preservation of the goods, packaging requirements, health and safety requirements, sales shelf display demands, economy, are in a composite flexible packaging design should first comprehensive consideration, the content of the packaging for different objects, we need to further deepen, refined, thinking. Various products on different to the requirement of composite packaging film, common has the following categories: 1] General industrial goods packaging: main consideration, protective packaging operations, sales of commercial, transportation, etc. ( 2] Daily chemical products packing: are mostly directly to consumers, to consider its protective, beautiful sex, convenience, shelf display, etc. ( 3] Electronics packaging: to consider its protective, anti-shock, anti-static, shielding and barrier property, etc. ( 4] The food and drug packaging: consider its health safety, barrier property, packing, shelf display and so on. Food packaging is the use of composite packaging film inside the main object, a wide range of different requirements, by packaging from birth to practice, from low to high temperature, from vacuum to inflatable packaging, almost covers all range of composite packaging film. ( 5] Packaging machinery parts: to consider its protective, functional, rust, transportation, etc.
