Of the 81 products actually sampled, there are 17 companies in the spot check. No samples were taken due to reasons such as production stoppages.

The spot check is based on GB9683 "Standards for Composite Food Bags", GB/T10004 "Plastic Composite Films and Bags for Packaging.

Dry compounding and extrusion compounding, GB/T18192 Paper-based composite materials for aseptic packaging of liquid foods, GB18454-2001 "Composite bag for aseptic packaging of liquid foods", GB/T18706 Paper base for liquid food fresh-keeping packaging "Composite materials", GB19741 "Plastic composite film for liquid food packaging, bags", QB2197 "composite film for mustard packaging, bags", BB/T0014 "zip chain ziplock bag", BB/T0039 "merchandise retail packaging bag" and other national standards And related standards require that the following items of food plastic packaging film bags be tested: tensile strength, breaking force, fracture nominal strain, inner plastic film peel strength, anti-pendulum impact energy heat sealing strength, water Vapor transmission, oxygen transmission, peel force, heat resistance, media resistance, pressure resistance of the bag, bag drop performance, seal strength, light transmittance, dart impact test, sensory, toluene diamine, Solvent residue, benzene solvent residue, evaporation residue, potassium permanganate consumption, heavy metals, decolorization test, etc.

The results showed that a batch of transparent vacuum bags produced by Shanghai Jinshuo Packaging Co., Ltd. (nominal) (specification model: 20cm × 25cm × 7 silk 4200; production date / batch number: April 11, 2016 /) was examined The oxygen permeability rate of the project is unqualified; 1 batch of compound bag (cooked) produced by Shanghai Donghan Industry & Trade Co., Ltd. (nominal) (specification model: 220mm×150mm; production date/batch number: January 28, 2016/) The total amount of solvent residues detected (mg/m~2|) failed.
