Sun Zhongjing: The packaging material tells you that for your food is not compliant

In recent years, China's meat processing industry has achieved rapid development. Various meat products have made important contributions to enriching and facilitating people's lives. In this important development process, emerging multi-layer co-extruded high-barrier packaging has made great progress in China. Multi-layer co-extruded high barrier packaging can be formed by co-extrusion at a time, and it has no pollution during the production process and has no impact on the environment. This kind of film, with its advantages of high barrier, high and low temperature resistance, no pollution and strong puncture resistance, will play a role in escorting meat product quality and food safety.

China’s total meat output ranks first in the world. However, the proportion, variety and quality of processed meat products are far from the developed countries in the world. Including meat food packaging technology, especially flexible packaging technology. For example, plastic packages of compound type currently occupy a considerable market share in the packaging of meat products. Composite packaging is a package of biaxially-stretched polyolefin materials combined with other materials (such as BOPA). They are composed of different materials, stretched films, and adhesives. They not only have poor barrier properties, but also because most adhesives contain benzenes and esters. Ketones and other harmful substances and odors, easy migration and infiltration of food. The state has conducted multiple quality inspections on food products. Some foods are unqualified due to harmful substances leaking from the membranes of the composite bags.

Composite traditional drawback is that workers Arts:

1) Multiple combinations may be required to achieve the overall demand for a packaging film. And co-extrusion can be formed just once.

2) Traditional compounding requires the use of glue materials, and most of the current glues are solvent-based. This may cause the solvent to remain. Coextrusion of all materials does not cause this problem.

3) Traditional compounding may cause VOC pollution in the production process and affect the human body.

4) Although the proportion of the main agent and the curing agent in the traditional dry compound glue water is designed, the adhesive layer has a certain amount of residual solvent in the manufacturing and compounding process. The substrate for food contact is usually a barrier material with low barrier properties such as PE or copolymerized PP. Some of the more permeable substances penetrate the substrate and enter the food, affecting the flavor and safety of the food and causing human health problems. Major influence.

If the coextruded barrier film can be used directly or as a substrate, it can also save materials, reduce processes, save costs, and can effectively block the penetration of solvents. Therefore, we advocate the use of co-extruded barrier films as the future packaging of meat products, which should be worth promoting.

"GB 9685-2016 National Food Safety Standards for Use of Food Contact Materials and Products Additives" is an important aspect of guaranteeing the quality of meat products packaging. The implementation of this standard has raised the safety of meat products to new heights. Food packaging materials cannot become "stealth additives" that result in unsafe meat products. Providing fresh, nutritious and safe meat products to consumers is the obligation and responsibility of food companies and packaging companies.

Multi-layer co-extruded multi-functional packaging film material can well meet the needs of various packaging occasions, but also has the advantages of dry composite film can not be compared, can replace dry composite film or reduce the number of dry composite, more environmentally friendly and energy-saving Features. By adjusting the thickness of the barrier layer and the use of a variety of barrier materials, it is possible to flexibly design thin films with different barrier properties, and also to flexibly replace and deploy heat seal layer materials to meet the needs of different packaging, replacing many with dry composites. The main packaging market. Therefore, the multi-layered and multi-functionalization of this co-extruded composite is the main direction for the development of packaging film materials in the future.

Nippon Synthetic Chemical Industry Co., Ltd. successfully developed EVOH materials in 1971 and began to promote the use of food packaging. EVOH material effectively solves the problem of oxygen transmission rate. At the same time, regarding the strength of the film, the Royal Dutch DSM Group established a high-quality nylon 6 production plant in China with an annual production capacity of nearly 90,000 tons. Shanghai Shengxiang International Trading Co., Ltd. communicates with customers and end users through long-term We hope to promote and promote the use of multi-layer co-extrusion technology, using EVOH and nylon to block raw materials, and with various types of auxiliary products, to produce more green and versatile packaging materials, so that our food less additives, keep fresh, Pure taste makes our food healthier and safer.
