FAQ
All products produced by our company are 100% biodegradable and compostable, and the raw materials used are also biodegradable. Our R&D center is dedicated to researching biodegradable polymers and making them into modified materials. Different products use materials suitable for their performance and make the best use of them.

Poly(butylene adipate-co-terephthalate) (PBAT) is a well-known biodegradable plastic. It is a flexible material and has a high elongation at break, as well as good hydrophilic and processing properties. PBAT has been widely used in the production of blown film and its associated membrane products. We use the PBAT + corn starch-based to make garbage bags, shopping bags, pet waste bags.

PLA can be described as biodegradable, but "under the specific conditions of industrial composting", it is more appropriate to say in this case that it is a biodegradable polymer. Under these industrial composting conditions, PLA can be biologically degraded within a few days, up to a few months. Customers who have requirements for toughness and transparency can use PLA as a raw material for handbag shopping bags and mailing bags which are tough enough, not easy to break, and close to ordinary plastic bags.

Polybutylene succinate (PBS) is a thermoplastic polymer resin of the polyester family. As PBS decomposes naturally into water and CO2, PBS is a biodegradable aliphatic polyester with properties that are comparable to polypropylene. The straws and tableware we produce are made of PBS, which is chemically stable and resistant to high temperatures. the applications of PBS could be found as disposable products such as tableware or medical articles.

When something is labeled at compostable, it means that the product “can” be turned into compost as long as it's under the correct conditions.


Compostable means that a product will break down into natural elements, but only in a compost setting. Compostable materials are typically made from plants and other organic materials, such as corn starch, bagasse, or PLA plastic. Compostable products have two added benefits over biodegradable options: they break down much faster, many in roughly 90 days, and they also break down into nutrient-rich products, which generates healthy soil for the planet.

  • Most of our plastic bags are customized according to customers drawing, logos, or ideas.
Traditional plastic is made from petroleum-based raw materials. Some say bioplastics—made from 20 percent or more of renewable materials—could be the solution to plastic pollution.

Bioplastics are plastics materials produced from renewable biomass sources, such as vegetable fats and oils, corn starch, straw, woodchips, sawdust, recycled food waste, etc. The term bioplastics encompass a whole family of materials that are biobased, biodegradable, or both.
Biodegradable: Biodegradation is the naturally-occurring breakdown of materials by microorganisms such as bacteria and fungi or other biological activity. These microorganisms eat away at the biodegradable material leaving behind only natural constituents of biomass, carbon dioxide, and water. Subsequently, these natural materials can be safely re-absorbed back into the earth.


Compostable: Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances. An ideal composting environment is subject to certain heat or moisture conditions. Decomposition of such materials results in the addition of rich nutrients to the soil and can be an effective form of fertilizer for home gardeners and farmers.


Degradable: Degradation (geology), lowering of a fluvial surface by erosion Degradation (telecommunications), of an electronic signal Biodegradation. Products are oil-based with an additive included to trigger the process of degradation – They are not biodegradable or compostable. Degradable materials break down via a chemical reaction and the end results of degradation do nothing more than break down the oil components into smaller fragments leaving behind the same amount of plastic dust. Degradable bags require specific UV conditions in order to break down and will remain intact when composted or buried in the landfill.
