Seasoning bags should meet the demand of which, are you sure you don't know! ！ ！

A, barrier property to oxygen in the environment of blocking ability - — By oxygen for excessive test verification, seasoning bags of oxygen excess larger ( The barrier property is poor) , easily lead to sauce, bone soup protein, fat, the composition such as oxidation caused by bacteria breeding, quality mildewy, bulge bag etc. Second, the uniformity of the thickness of the physical and mechanical properties - — Validated by testing the thickness of the seasoning bags, and the uniformity of the thickness of the seasoning bags good performance is the basic. Flexibility - — Through the tensile elongation and modulus of elasticity, pendulum impact resistant to two experiment with common validation, prevent seasoning bags due to the brittleness and less prone to resistance bag pressure, thus produce the problem such as broken bag. The grease resistance - — By not packing seasoning bags and have seasoning bags, peel strength, tensile elongation compared with elastic modulus test validation, prevent composite bags for resistance to grease, and appear between each layer in the composite membrane film composite fastness, and even produce the problem such as packet delamination and the decrease of the barrier property. Smooth - — Validated by the coefficient of friction test, prevent the finished bag the whole cooking sterilization bags because of high temperature resistance is poor, lead to delamination, cooking after sterilization bags shrivel 5, torn bags, and other issues. Compression performance - — Through compression test verification, to prevent finished seasoning bags torn bags without resistance to outside pressure. Residual solvents, health performance -- - — If validated by solvent residual test, solvent residue is overmuch, bags have peculiar smell, and residual solvents in high temperature environment are more likely to migrate to the seasoning, cause its peculiar smell, and affect the health of consumers.
