Biodegradable and environmentally friendly PLA straw

Biodegradable plastic cup covers, knives, forks, spoons, straws, and plastic cups used in catering supplies are produced from polylactic acid PLA and are biodegradable, meeting the requirements for food contact grade materials. The demand for plastic tableware has shifted from non biodegradable materials to biodegradable materials. Currently, non biodegradable plastic products on the market mainly include PP/PET/PS cup caps and matching products for plastic cups. With the popularization of environmentally friendly and biodegradable polylactic acid materials in catering straws, cups, and bottle caps, the use of traditional non degradable catering supplies has gradually decreased, making a contribution to environmental protection.

Environmentally friendly PLA straw is suitable for cold and hot drinks. There are also differences between thick and thin pipes, as well as between straight and curved pipes. The length can be long or short, and the diameter can be large or small. The following are the reference technical indicators:

1. Fully biodegradable straw for cold drinks, size: 6mm OD x 210mm length, temperature resistance: 50 ° C.

2. Mild resistant and fully biodegradable straw: hot drinks such as coffee and milk tea, size: outer diameter 12mm x length 220mm, temperature resistance: 80 ° C, quantity: 100 pieces/bag.

Currently, the plastic tableware used in the beverage industry mainly includes cup caps, plastic cups, knives, forks, spoons, straws, and so on. Environmentally friendly and biodegradable PLA straw can be made into different specifications according to downstream requirements, with good biodegradability and usability. With the establishment of "carbon peak" and "carbon neutral" goals, low-carbon economy has become a trend. Biodegradable plastics can form a complete closed loop through "biomass based product recovery or combustion of CO2 biomass" to reduce greenhouse gas emissions, thereby reducing the carbon emissions of plastics generated by current petroleum routes. According to Yuan Su's information, the carbon emission coefficient of PLA products is far lower than petroleum based plastic products such as PE, PP, PBS, and PBAT.

A simple knowledge extension of polylactic acid (PLA), the basic material of environmentally friendly PLA straw: PLA refers to polylactic acid, also known as polylactic acid, which is a polymer polymerized from lactic acid as the main raw material, and is a biodegradable material based on biology. CPLA refers to crystalline PLA with a higher heat resistance temperature than PLA.
