复合膜-食品包装的又一次飞跃
复合膜-食品包装的又一次飞跃
There are many kinds of packaging materials, but there are great differences in performance.
Although it has many excellent properties, 可在一定范围内使用, 但单一材料不可能具备包装材料的所有性能, 不能满足食品包装的整体要求.
所以, according to the different purpose of use, the different packaging materials are combined to make it have a variety of comprehensive packaging performance, composite packaging materials are thus produced.
Composite film packaging material refers to two or more layers of different kinds of flexible materials, through a certain combination of technology.
“Structured” multilayer materials. The composite substrates are plastic film, aluminum foil and paper.
Composite packaging film, has become the most important category of food packaging materials, is the development direction of food packaging.
Composite film has two advantages incomparable to single film:
- Good comprehensive packaging performance.
Composite film, which combines all the single film properties that make up composite materials,
With high barrier, 高强度, good heat sealing, high resistance
Temperature and packing operation adaptability.
- Good health and safety performance.
The printing layer can be placed in the middle, with non-polluting contents and protection
Protect the role of printing decorative layer.
The structural requirements of composite film for food inner packaging:
- Inner layer requirements: 无毒, 无味, oil resistance, 耐化学性
好的, with heat sealing or adhesion. Commonly used inner layer has PE,
CPP, EVA, ionic polymer and other thermoplastics. - Outer requirements: good optical properties, good printability, wear and heat resistance, with strength and rigidity. The commonly used outer layer is PA, 宠物, 双向拉伸聚丙烯, PC, aluminum foil and paper.
- Intermediate layer requirements: with high barrier (Yang xiang, anti
Damp and shade), among which aluminum foil and PVDC are the most commonly used products
Kind of.
The representation of composite film:
From left to right are the outer layer, middle layer and inner layer materials,
例如: paper /PE/AL/PE, outer layer provides printing performance, medium
The intermediate PE layer acts as a bond, and the intermediate AL provides barrier and stiffness
Degree, inner PE provides heat sealing performance.
