The safety of food contact materials has been widely concerned. SIJIA Technology R & D Center has upgraded the safety performance of SIJIA new PVC materials and developed the food contact grade PVC materials.

Tested and approved by SGS, SIJIA food contact grade PVC materials meet GB 4806.7-2016 "National Food Safety Standard for Plastic Materials and Products used in contact with food" standard, and pass the US national Food safety standard FDA 21 CFR 175.300 test, meeting the requirements of food contact material safety standard.

SIJIA can provide two kinds of food contact grade PVC materials: composite fabric type and film type.

With high tensile,tearing and adhesion strength, composite fabric type can be used in the manufacture of drinking water storage and transport water bags, cleanable aquaculture tank, etc.

The film type is suitable for making food storage bags and can also be used for drinking water storage and transportation and other scenes.

SIJIA Food contact grade PVC material, its safety is comparable to TPU material, but better weather resistance. It can adapt to outdoor high and low temperature changes, sun exposure and other situations, especially not easy to aging, can be used for long life in the dry area.
