New process for plastic flexible packaging film

Active plastic film

An Australian company has developed an active plastic packaging film that enables perishable products such as packaged fresh fruits, vegetables and flowers to maintain their freshness for several weeks, and better solve long-distance transportation of these products. problem. This good-keeping packaging film is a breathable film that allows the generated carbon dioxide and oxygen to permeate, keeping the perishable product asleep. The film is impregnated with organic chemicals and can absorb ethylene that promotes the ripening of fruits and vegetables, and keeps the surrounding of perishable products moist. At the same time, the film contains trace amounts of slow-release fungicide and can prevent the growth of mold. Therefore, the freshness of packed fruits and vegetables can be extended by more than 1 time.

Heat shrinkable film

The competition for plastic films has become increasingly fierce. People are paying more attention to the better shrinkage and lower cost of films. Many companies have introduced polystyrene resins with better performance. There have been shrinking films processed from raw materials such as corn, which are highly environmentally friendly and recyclable. In addition, the low shrinkage OPP film has a great market, it can easily integrate into the company's existing recycling system. Recently, heat-shrinkable film labels have become popular in consumer packaging, and PVC film has a large market share.

Coextruded film

Co-extruded films are the latest technological trends in the packaging film industry. The film uses ordinary inks and coatings, has high barrier properties, better transparency, heat sealability and layout printing flexibility, can be used as a plasma coating material. The development of co-extruded packaging film will change the product structure of the multifunctional film and is suitable for food packaging such as beverages, milk and fresh meat. The co-extruded packaging film in developed countries accounts for about 40% of all soft plastic packaging films, while China accounts for only about 6%.

Edible film

This film is a film with a porous network structure formed by natural edible substances (such as polysaccharides, proteins, etc.) as raw materials, through the interaction between different molecules, and can be applied to the inner packaging of various ready-to-eat foods in foods. The industry has a huge market.

Degradable film

This kind of film mainly solves the difficulty of recovery of certain non-degradable packaging materials, buried in the ground will destroy the soil structure, and incineration treatment will produce toxic gas and cause air pollution. The biodegradable plastic packaging film not only has the functions and characteristics of the conventional plastic, but also can be degraded in the natural environment through the action of microorganisms in the soil and water or the action of ultraviolet rays in sunlight after the service life is completed. Degradable plastic products have been used in packaging applications such as general packaging films, shrink films, shopping bags, garbage bags, etc., and play an active role in improving the environment.

Water soluble film

Water-soluble plastic packaging film as a novel green packaging material is widely used in the packaging of various products in Europe, America, Japan and other countries. Water-soluble films have received attention from developed countries in the world due to their environmental degradation such as thorough degradation and safe and convenient use. At present, foreign countries, mainly Japan, the United States, France and other countries, produce and sell such products, and domestic companies have already put into production. Their products are moving toward the market.
