Since the first batch of
PLA coated paper cups were put on the market in early 2006, a proven technically and commercially viable alternative to traditional plastic-coated paper has been available.
At present, less than 5% of the hot paper cups used worldwide each year (about 4 billion) are coated with PLA.
PLA coated cups do cost more than traditional cups, but the difference is only a few cents per cup on average. Small price to pay for convenience Drink your favorite beverage while on the road, using sustainably produced products that can be diverted from landfills.
Background of Pla coated paper cup
Disposable paper cups are mainly divided into wax cup, straight wall double layer cup and
polyethylene coated cup according to the coating on the inner wall of paper cups. Polyethylene coating glass is covered with polyethylene coating on glass, belongs to the newer technology, advantage is cold and hot drinks can rise to the occasion, and the surface is smooth, non-toxic tasteless, although polyethylene itself but for a long time under the condition of heat, the material or processing technology does not pass, if choose polyethylene easy oxidation of carbonyl compounds, Carbonyl compounds are not easy to volatilize at room temperature, but they may be volatilized when hot water is introduced into the paper cup, which makes people smell an unpleasant smell, and long-term intake is harmful to human body. And polyethylene can not be biodegradable, easy to cause environmental pollution.
At present, the disposable paper cup made of polylactic acid coated paper has the characteristics of biodegradable, non-toxic and harmless, which overcomes the problems of the polyethylene coated cup. It is safe, environmentally friendly and sustainable, in line with the green cycle criterion of endless life and growth, and is loved by the majority of consumers.
Regarding the material, PLA coated paper
PLA coated paper (biodegradable coated paper) itself is an environmentally friendly product that is completely decomposable and compostable. Polylactic acid (PLA) is a new type of biodegradable and environmentally friendly material, which is made from starch raw materials proposed by renewable plant resources (such as corn). Starch raw materials are saccharified to obtain glucose, which is then fermented by glucose and certain strains to produce high-purity lactic acid, and then a certain molecular weight polylactic acid is synthesized by chemical synthesis. It has biodegradable and compostable thermoplastic materials. It uses plants as the main source of raw materials; it is a 100% fully biodegradable material that is extracted, fermented and polymerized. It can be completely biodegradable by microorganisms in nature in a composting environment. Degraded into carbon dioxide and water needed for plant growth. It has good biodegradability and does not pollute the environment, which is very beneficial to the protection of the environment. It is a common environmental protection material abroad. Compared with traditional PE coated paper products, PLA coated paper products can be recycled after use. The special and diversified recycling method of renewable resources greatly reduces the burden on natural resources and the environment, which is in line with hygiene. The endless green cycle principle.
The
PLA paper cup is the emergence of new technology and new technology, which has continuously improved the manufacturing technology of paper cups. New types of paper cups will appear and play a greater role in promoting and promoting the variety of products. The surface of the hot drink paper cup should be treated with wax spray or dip wax. Because cold drinks will cause water on the surface of the paper cup, the paper cup will soften, and it will be waterproof after being coated with wax.
Replacing traditional plastics with PLA to produce disposable food service disposable packaging provides many environmental benefits.
PLA coated paper cups are commercially compostable. Allow packaging and any food scraps to be transferred from the landfill. This material dissolves in the paper recycling process without special equipment. If you are interested in disposable
PLA coated paper cups, please contact Hyde.
