Wood powder plastic Japanese technology personnel developed a wood flour plastic packaging material from pine wood. This material is produced by removing the polyol from wood flour and reacting with isocyanate to produce polyurethane. This wood powdered plastic is extremely heat resistant and can be biodegraded and can be used to make temperature-resistant packaging bags.
Bactericidal Absorption Plastic Bags The Russian Institute for Practical Biotechnology has recently developed a plastic packaging bag that can absorb water, sterilize, and can be reused many times, allowing foods, such as cheese and sausages, to be easily degraded for longer periods of time. Russian experts have added dehydrated mineral salts and enzymes to plastic polymers. The inner surface of the plastic bag, which is rich in these substances, absorbs excess moisture and kills bacteria, thus improving the internal environment of the packaging bag. The enzyme in the additive also regulates the odor of the food, creating a bottom-up space for nutrients in the food. This new type of plastic bag can be used repeatedly and can be used repeatedly under specific conditions for nine times, thereby reducing the packaging cost and reducing the production cost.
Straw container Disposable straw catering container uses pure natural plant fibers such as abandoned crop stalks, adds safe and non-toxic molding agents that meet the hygienic standards of food packaging materials, and can be completely degraded green environmental protection products through unique processes and molding methods. The product is oil-resistant, heat-resistant, acid-alkali-resistant, and freeze-resistant. The strength is better than foam plastic and paper cutlery. The price is much lower than paper cutlery. The tableware not only eliminates white pollution, but also provides an effective way for the comprehensive utilization of straw.
A new kind of special film for detecting bacteria, which is newly developed by the EM film, is coated with a special coating on the surface of the ordinary food packaging film to enable it to detect special functions of bacteria. For example, in the case of the biofilm used for raw and cooked meat packaging, if the packaged meat is not fresh and the harmful bacteria content exceeds the food hygiene standards, packaging with this film will make the original transparent and colorless film become a warning. Color, so that customers immediately know that the contents are no longer edible.
Not long ago, corn plastics researchers in the United States developed a corn plastic packaging material that is easily decomposed. It is made by incorporating cornstarch in polyethylene. This plastic is suitable for making food and packaging integrated bags. The package not only dissolves quickly in water, but also avoids contamination and bacterial infections.
Rapeseed Plastic A rapeseed plastic packaging material was recently developed by the United Kingdom. It extracts three genes that produce plastics from bacteria that make biopolymers, and then transfers them to the rapeseed plants. After a period of time, it produces a plastic polymer liquid that can be processed to obtain a rapeseed plastic. , Packaging materials made from such plastics or food fast food packaging materials can be decomposed spontaneously after being discarded without contaminating residues.
Wheat plastic This is the use of wheat flour added glycerin, glycol polysilicone oil and other mixed dry, and then heated by 150 kg per square meter hot, plastic plastic film becomes translucent. The advantage of packaging foods with wheat plastics is that they can be decomposed by microorganisms after use.
Bacterial plastics British researchers recently developed a bacterial plastic called PHB. It uses sugar to grow a kind of bacteria, and then it is processed to make it similar to polypropylene. This material is non-toxic and biodegradable. It is an ideal material for processing food packaging bags. At the same time, it has no pollution to the environment after disposal.
