Food packaging film materials are those?

- Jan 04, 2018 -

Food packaging film materials are polyhydroxyalkanoate (PHA), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) and polycarbonate (PC) and so on.


First, the material selection:


   Environmental Options - Polyhydroxyalkanoates (PHA); Food Bags Options - Polyethylene (PE)


    Fresh choices - Polyvinyl chloride (PVC); Fatty food choices - Polypropylene (PP)


Second, five kinds of materials:

1, polyhydroxyalkanoate (PHA) material


Is a kind of biological polymer material, is a kind of intracellular polyesters synthesized by many microorganisms, and is a kind of natural polymer biological material.

With biodegradability and the thermal processing properties of plastics, materials tend to have high water vapor permeability, which is detrimental to food preservation.

PHA has a good gas barrier properties, making it possible to apply fresh products for a long time on the packaging.

2, polyethylene (PE) material


Good water resistance and moisture resistance, poor resistance to organic vapor of gas barrier, good chemical stability, no reaction with general acid and alkali at normal temperature, and poor oil resistance;

Have a certain mechanical tensile and tear strength, good flexibility, low temperature.

3, polypropylene (PP) material


Barrier than PE, strength, hardness, rigidity higher than PE;

The main film made of food packaging materials, suitable for packaging oily food.

4, polyvinyl chloride (pvc) material


Poor thermal stability, poor fluidity in the viscous flow state, adding plasticizer to improve the performance;

Gas barrier oil resistance, gloss than PE, generally used for fresh fruit and vegetable packaging.

5, polycarbonate (PC) material


Difficult to dissolve crystalline, with good transparency and mechanical properties, low temperature impact resistance;

But expensive, injection molding can be pots, boxes, blow molding bottles, cans and so on.
