The use of food packaging

The commonly used packaging materials and containers for food blister include paper, plastic, metal and glass. In addition, there are wooden Dongguan Chang'an Blister Factory.


Food packaging materials should have the following functions:

(1) The protective food shall have various technical properties required for the protection of food, such as corresponding air permeability, moisture permeability, chemical stability, physical and mechanical properties, sealing (measured by sealing tester), light shielding, fragrance retention, etc.

(2) The adaptability of production process can meet the requirements of packaging mechanization and automatic production process, such as the operation performance of sterilization, molding, filling (sometimes hot filling) and sealing of materials, so as to ensure the production efficiency and packaging quality.

(3) Promoting the sales of packaging materials and containers should have good sales appearance and adaptability of printing and decoration, which will help to improve the value of food products and be attractive and competitive in the market.

(4) Health and safety food packaging materials shall not have any adverse impact on food, including any odor and pollution of harmful ingredients, to ensure the health and safety of food, and at the same time, to make consumers have a sense of safety and health Dongguan Chang'an plastic factory.

(5) Other packaging economy, saving resources, energy and packaging waste recycling, environmental health and ecological balance and other long-term issues.


Classification of food packaging materials

The packing belt is made of PP and pet. Main production process: melting of plastic particles - pressing belt - forming - cooling - winding - Packaging - warehousing packing belt is a net structure packing material produced by polypropylene through heating, melting, stretching and cooling. The basic parameters affecting the quality of packing belt are tensile force, length, bending degree, elongation, etc. Under the same tension and other parameters, the longer the length, the lower the cost. Hangzhou Yongchuang introduces four of the world's most advanced packaging belt production lines, using processing technology, to produce high-strength, high-quality, environmental friendly 3000m new material packaging belt. The unit price cost per meter of packaging belt is far lower than the unit price of domestic return belt and similar import belt, and the cost is reduced by 120%. Dongguan Chang'an blister plant.


Introduction of winding film

PE winding film is an industrial film product with high tensile strength, high elongation, good self adhesion, high transparency and other physical points. It can be used for manual winding film, machine winding film and centralized packaging of various goods.


PE winding film is mainly made by mixing and extruding several different brands of Polytechnic resin. It has the advantages of puncture resistance, super strength and high performance. It is widely used in the export of foreign trade, papermaking, hardware, plastic chemical industry, building materials, food and medicine industries to wrap and pack the goods stacked on the pallet, making the packing more stable and clean, and more super waterproof.


PE stretch winding film and PE slitting winding film: LLDPE stretch winding film is made of high quality LLDPE as the base material, plus high-quality tackifier, after heating, extrusion, tape casting, and then cooling by the chilling roller. It has the advantages of strong toughness, high elasticity, tear resistance, high viscosity, thin thickness, cold resistance, heat resistance, pressure resistance, dust prevention, water resistance, single side adhesion and double side adhesion. It can be used It is widely used in papermaking, logistics, chemical industry, plastic raw materials, building materials, food, glass, etc.
