Plastic products are notorious for leaching toxic chemicals into food. This is because disposable plastics are treated with chemical mixtures including dyes, bleach and ink.
Some of these products are safe and some are not so safe.
On January 16, 2020, China promulgated the opinions on further strengthening the Control of plastic pollution (plastic ban). Since then, various provinces and cities have issued plans for the treatment of plastic pollution. Relevant regulations have been made to prohibit the use of disposable plastic straws, plastic bags, plastic tableware and hotel supplies. Disposable straws made of biodegradable materials are more environmentally friendly because they do not leave toxic chemicals or residues. In addition, over time, these products will degrade and release nutrients that are good for the earth into the soil. However, we should pay attention to the safety of food contact even straws are made from biodegradable materials.
BOXAI independently developed CPLA milk tea straw, not only heat resistance can reach 100C, the level of food safety is also much higher than the PLA+PBS straw in the market.
Plastic bags do bring convenience to our life, but this temporary convenience brings long-term harm. The recycling value of plastic bags is low, in addition to the 'visual pollution' pollution caused by scattered in urban streets, tourist areas, water bodies, roads and railways, it also has potential harm. The structure of plastic is stable, it is not easy to be degraded by natural microorganisms, and it is not separated in the natural environment for a long time.
The plastic restriction order, which came into effect on June 1, 2008, clearly stipulates that shopping malls, supermarkets and bazaars are not allowed to provide free plastic shopping bags, and prohibit the use of plastic shopping bags less than 0.025 mm thick. After the implementation of the plastic restriction order, it has achieved certain results and promoted the development of the environmental protection plastic bag industry to a certain extent.
PBAT is a kind of thermoplastic biodegradable plastic, which is a copolymer of butylene adipate and butylene terephthalate, which has the characteristics of PBA and PBT. It not only has good ductility and elongation at break, but also has good heat resistance and impact properties. In addition, it also has excellent biodegradability and is one of the best biodegradable materials in the research and market application of biodegradable plastics.
Compared with traditional PE and PP materials, PLA has higher melting point and better processability. The hardness and mechanical properties of PLA are similar to those of traditional resin (such as PS). It has good transparency and excellent gloss, so it is more suitable to be used as packaging material.
