Food packaging manufacturer: food packaging testing

Packing: food packaging testing of food packing single membrane bag inspection items are divided into the following categories: food packaging appearance may not have to use the hindrance of bubbles, perforation, water lines, critical reinforcement, plasticizing, fisheye frozen block to prevent disease. Specifications, width, length and thickness deviation are due within a prescribed scope. Physical and mechanical properties including tensile strength, elongation at break, is it reflect product in use process along with the ability to stretch, if this is unqualified, in use process food sack prone to rupture, damage phenomenon. Food packaging composite film bags of inspection items are divided into the following categories: appearance should level off, without cut, burn, bubbles, and oil, and wrinkle, heat sealing level off, without a virtual closure. Film can not have crack, pore and composite layer separation. Without impurities, foreign bodies, and oil and pollution. Bag soaking liquid, can not have odor, odour, turbidity and decoloring phenomenon. Second, the physical and mechanical properties including tensile strength, elongation at break, is it reflect product in use process under tensile ability, if this is unqualified, in use process rupture is prone to food packaging bags, damage phenomenon. In addition to include gas barrier property indexes such as volume through the air; Oil resistant degree index, heat resistance, cold-resistant, medium resistance; Bag sealing stripping force, bag, such as pressure and resistance to fall indicators, the indicators reflect the reliability of the food sack packing materials inside the protection. The processing of plastic film bag must after heating the checkpoint, and at the time of the heated plastic cracking, oxidation and degradation, bad problem, therefore, when use resin processing plastic film or bag, to join in the resin antioxidant, heat stabilizer and other additives. Some packaging film bag as a result of the need of packaging technology and mechanical or contents also requires high anti-static, prevent dewing, smooth, so also want to join the antistatic agent, antifoggant, lubricants, opening agent such as additives. All of these additives, the first thing to the GB15139 'food safety toxicology evaluation procedure of the test, prove just can use non-toxic, but there is also an added amount limit. So, in the products, these can be extraction of low molecular weight material, namely evaporation residue, or can be the oxidation, potassium permanganate consumption, cannot exceed the prescribed amount, can't use more than. For FRP products, therefore, must have the corresponding health standards, its purpose, is to prevent abuse and misuse of additive, is to ensure better direct food packaging and contact materials with high health and safety performance. At present, the technical standard stage of development in flexible packaging is not adapt to the development of industry products, such as flexible packaging composite material structure is developing rapidly, just use the material is PE, PP, PVC, PVDC, PET, PA, EVOH, EVA, EEA, EMA, ion polymer as well as a variety of printing ink, adhesive and so on dozens of materials, the existing standard of compound packing materials involves only BOPP, LDPE, BOPA, PET, aluminum foil and other materials, and many other structure of the composite film materials inspection can be depended on the top, only with reference to the existing standards and related standards. Secondly composite flexible packaging new post-processing method is used in the roll out, according to different packaging different contents and application field and there are many requirements, such as in the field of food packaging, in addition to the traditional pasteurization, boiled, cooking, cooking, 135 ℃, 121 ℃ microwave packaging, vacuum packaging, different applications such as the physical and chemical effect of the composite film bag and often boiled heating is not the same, so there is only cooking membrane bags technical standards not enough,. And the composite flexible packaging raw and supplementary materials such as various kinds of thin films, adhesives, solvents, additives have many lack of corresponding industry standards or national standards. Perfect packaging film bag industry and the national standard and strictly implemented, to strengthen the inspection supervision of food packaging, to prevent unqualified food packaging into the market, and coordinated, strengthen management, guarantee the healthy development of the flexible packaging industry.
