What are the materials for producing plastic water cups? PLA (Part 1)

Hello everyone, "Dong Dong Talk Cup" is here. I started by sharing the materials for producing plastic water cups, and talked about PP, PC, AS, and PS one after another. Today I will continue to share PLA. http://www.zhanyict.com/en/ProductsDetail-VB-10020.htmlOriginally, I wanted to share other plastic materials before sharing PLA with you, but recently I received a lot of messages from friends saying that the materials I shared before were non-degradable and harmful to the natural environment. Is there a material that is food grade, safe and healthy, and at the same time naturally degradable and will not cause harm to the environment? So I decided to share PLA with you in advance.

Nowadays, the improvement of environmental awareness is not limited to Europe and the United States, but the whole world is showing an overall improvement, which has also prompted more companies, brands and consumers to choose more eco-friendly materials and products. In the water cup industry, http://www.zhanyict.com/en/ProductsDetail-VB-10020.htmlamong the materials that can meet the requirements and are relatively stable, PLA (polylactic acid) has become a popular choice in the plastic water cup manufacturing industry due to its biodegradability.

What are the characteristics of PLA?

PLA, or polylactic acid, is a renewable bioplastic obtained by fermenting plant resources such as corn starch. It is one of the most commonly used bio-based degradable plastics.

Biodegradability and compostability: PLA can be completely degraded within a few months in an industrial composting environment, converted into water and carbon dioxide, http://www.zhanyict.com/en/ProductsDetail-VB-10020.htmlwhich greatly reduces environmental pollution.

PLA has good transparency and can produce products that look similar to traditional PET plastics.

PLA can be processed by common plastic processing techniques such as injection molding, blow molding, thermoforming, etc., and the processing temperature is lower than that of traditional plastics.

What are the advantages of PLA?

Environmentally friendly, its biggest advantage is its biodegradability. After use, it can be completely decomposed under appropriate conditions, reducing long-term pollution to the environment.

Renewable source: PLA comes from renewable resources, such as corn or other plants, http://www.zhanyict.com/en/ProductsDetail-VB-10020.htmland does not involve petrochemical resources, which is in line with the sustainable development strategy.

Energy saving: lower energy consumption during the production process compared to traditional plastic manufacturing.

What are the disadvantages of PLA?

Cost: PLA is more expensive to manufacture than traditional plastics, mainly due to raw material costs and complex production processes.

Poor heat resistance. PLA has a low heat deformation temperature of about 60°C and is easily deformed at high temperatures, http://www.zhanyict.com/en/ProductsDetail-VB-10020.htmlwhich limits its scope of use.

Physical properties: PLA has lower strength and toughness than many traditional plastics and may perform poorly under load and impact.

Due to space constraints, today’s sharing ends here. The editor will share the rest of the content with you tomorrow. Thank you for your continued attention, and see you next time.
