The rubbing resistance of the aluminum-plated composite film can be improved by increasing the bonding fastness between the aluminum-plated layer and its base film, increasing the thickness of the aluminum-plated layer, etc., and promptly inspecting the oxygen permeability of the aluminum-plated composite film packaging before and after rubbing. Quality screening for rate change
Therefore, all manufacturing companies should strengthen regular testing of the water vapor transmission rate of waterproof and breathable membranes.
How to solve the problem of damage to the plastic woven bag body? The service life of plastic woven bags is very important, so manufacturers should strengthen the testing of the tensile strength of plastic woven bags.
Therefore, the abrasion resistance of the ink layer of paper printed matter cannot be ignored.
Therefore, enterprises should strengthen the monitoring of toughness-related indicators of POF shrink film to ensure its excellent toughness.
Therefore, research and testing of the water vapor transmission performance of latex paint is one of the important ways to improve product and construction quality.
it is necessary to strengthen the testing of moisture-proof performance of instant noodle packaging.
Therefore, by testing and comparing the barrier properties of aluminized composite film packaging before and after rubbing, the rubbing resistance of the packaging can be effectively controlled to prevent the above quality problems of potato chips caused by poor rubbing resistance of packaging materials.
Monitoring the residual oxygen and carbon dioxide content in the packaging is not only one of the effective means to ensure good drug quality, but also can be used as a basis for determining the shelf life.
Strengthening the testing of packaging impact resistance is of great significance to reduce the rate of packaging bag breakage.
Therefore, the detection and control of the friction coefficient of polyethylene shrink film is an effective way to improve its performance, and it is also a basic requirement of the standard.
