Plastic is a kind of macromolecule material made with high molecular polymer resin as the basic component and adding some various additives to improve performance. Plastic bottles are now used as packaging materials
A sign of the development of modern packaging technology is the fastest development in the world in 30 years. A new packaging material with a huge site, it is widely used in food packaging and has largely replaced glass, metal, and paper
Other traditional packaging materials have become the most important packaging materials for food sales packaging.
The superior characteristics of plastic bottles used in food packaging are:
①Plastic bottles are light in weight and have good mechanical properties. The strength calculated according to the unit mass of the material is high, so the packaging containers and products made are light-weighted, convenient for storage and transportation, and easy to carry. plastic bottle
The good mechanical properties of packaging materials make it convenient for molding processing and packaging operations, and high-speed automation of food packaging.
②Plastic bottles have good barrier properties. Choose suitable plastic packaging materials. It can meet the sealing requirements such as gas barrier, fragrance, waterproof, and moisture-proof of food packaging, and can also meet the requirements of hygiene
Certain air permeability requirements for modified atmosphere preservation packaging of fresh food.
③The molding processing performance of plastic bottle packaging products is good. It can be processed into films, sheets, ribbon fabrics and containers of various shapes, suitable for the packaging of various physical foods and various other
The need for packaging. Plastic packaging materials have good sealing properties such as heat sealing, and are easy to composite with other materials to make up for the shortcomings of the packaging performance of a single material, and the composition has an excellent comprehensive
Composite packaging materials for packaging performance.
④The plastic bottle has good decorative performance. Plastics can be made into transparent packaging materials to reflect the visibility of the packaging. It can also be used for packaging exquisite patterns and bright colors by coloring and printing.
Color, improve the display effect of the product, thereby establishing the image of the product. Promote sales.
⑤Good chemical stability. Health and safety. Plastics can withstand the corrosion of general acids, alkalis, salts and greases. Most plastic packaging materials can meet the hygiene and safety requirements of food packaging.
begging. With the development of modern science and technology, the variety of plastics is increasing, which greatly promotes the development of new composite materials and their application in packaging. Development and new technology of new food packaging materials
The application of technology has greatly changed the appearance of food packaging. Refined container shapes, novel packaging forms, and exquisite printed packaging are emerging in an endless stream. All these not only improve the food packaging
The protective effect of food products, and the abnormal appeal and temptation to consumers, has greatly promoted the development of the food industry and the transformation of sales methods.
