The original packaging sprouted in the Paleolithic era of the primitive society. Plant leaves, husks, hides, animal bladders, shells, turtle shells and other items to contain food and water. These parts of animals and plants, which have almost no technical processing, are not really packaging, but in terms of packaging, they are already in the bud. Modern packaging design is equivalent to the end of the 16th century to the 19th century. With the advent of industrialization, a large number of commodity packaging has led some fast-growing countries to begin to form machines for the production of packaging products. Modern packaging design, in essence, began after the 20th century. With the globalization of commodity economy and the rapid development of modern science and technology, the development of packaging has entered a new era.

Modern plastic packaging - opening new miles in composite packaging
Plastics are based on synthetic or natural polymer resins. After adding various additives, it has ductility under certain temperature and pressure, and can fix a kind of material of its shape after cooling. The process of natural or synthetic polymer resin molecules in a molten state and uniform distribution of auxiliary molecules around them is called plasticization. This process has been achieved, which has been plasticized, has not yet been reached, and is considered to have not been plasticized. Plastic packaging is one of the four major materials in the packaging industry: paper and cardboard account for 30%, plastics for 25%, metal for 25%, and glass for 15%.
High barrier film
The high-barrier film is a film having a multilayer structure in which a material having a high gas barrier property is extruded simultaneously with a polyolefin having high heat-seamability and moisture barrier properties. By using a high barrier film, it is possible to prevent microbial growth due to penetration of gas such as oxygen; to prevent oxidation of contents due to oxygen permeation; to prevent outflow of flavor, solvent, etc., and to improve the storage property of the contents. The high barrier film should also have a strong water vapor barrier property to prevent mildew of the contents due to the penetration of moisture. It is mainly used for the packaging of food products such as meat processing products (ham, sausage, fresh fish jelly, clam meat), raw meat, cheese, salad dressing, sauces, agricultural products and seafood processed products.
Plastic packaging has been widely used in food, electronics, beverages, alcohol, tea, coffee, medicine, health products, cosmetics, small appliances, clothing, toys, sporting goods and other industries and product packaging and other industries, plastic packaging from Early single-layer materials and simple printing have evolved into a perfect form of double or multi-layer material composite and multiple color printing, which greatly enhances the quality and added value of product packaging, thus promoting the markets colorful and prosperous.
Pure aluminum film has good light-shielding property, strong reflection ability to light,good barrier, moisture-proof property.
The metalized film are high strength, good temperature and chemical resistance, good anti-aging properties.
Coated paper can be used directly for printing, or it can be used in combination with PET, OPP or PE.
Kraft paper can be used directly for printing, or it can be combined with PET, OPP or PE for bag making.
Composite packaging gradually replaces simple packaging with its perfect printing effect and high barrier properties
Beautiful printing, good barrier
Diverse composite structure
Two to four layers of composite structures are more common,Can be vacuumed or retorted
Composite packaging application
Automatic packaging Dried fruit, coffee, tea, etc. Red wine, juice, laundry detergent, etc. Daily, medicine, etc. Anti-static products such as electronics
For food,coffee,cosmetics packaging
For detergent,hand soap,juice and so on
For dry food,coffee,tea and so on
For wine,juice,drinking water and so on
