Everyone's Favorite PLA Biodegradable Straws

PLA degradable straws are made of a new type of bio-based and renewable biodegradable material called PLA, also known as polylactic acid. It is made from starch raw materials proposed by renewable plant resources (such as corn, cassava, etc.), and is degradable. Ordinary plastic straws are not degradable.

1. PLA organic straws use renewable plant resource lactic acid as raw material

It has the advantages of renewable raw materials, completely degradable and biosafety. It is a project developed on the basis of traditional polypropylene (PP) straws in recent years. The production process is simple and the production cycle is short. It adopts a one-time extrusion molding process, and with the help of the extrusion action of the screw, the heated and melted PLA particles are extruded through the die of the die, cooled and shaped in the water tank, and then cut into various sizes of straws.

2. PLA organic straws have good biodegradability

PLA organic straws do not pollute the environment and can meet the needs of industrial composting. The straw extruded at high temperature has good thermal stability and good solvent resistance. Its product gloss, transparency and hand feel can replace petroleum-based products. The physical and chemical indicators of the product can meet the requirements of local food safety regulations. Require. Therefore, it has a wide range of applications and can basically meet the needs of most beverages on the market.

3. PLA organic straws have good moisture resistance and airtightness

The performance is stable at room temperature, but it will automatically decompose when the temperature is higher than 45 ° C or under the action of oxygen enrichment and microorganisms. Special attention should be paid to the temperature during the transportation and storage of the product. Prolonged high temperature will cause deformation of the PLA straw. PLA organic straws are limited by the performance of raw materials, and cannot be used for hot drinks during use, but are suitable for cold drinks.

4. The raw materials of PLA organic straws are natural raw materials such as corn or starch

Since corn and starch are a kind of biodegradable natural polymer, they are decomposed into glucose under the action of microorganisms, and then decomposed into water and carbon dioxide. The generated carbon dioxide directly enters the soil organic matter or is absorbed by the plants, and will not be discharged into the air and will not cause a greenhouse effect. Effectively avoid the problem of white pollution caused by plastic products, PLA organic straws truly originate from nature and belong to nature.
