• Q:What is the difference between biodegradable plastic bags and non-degradable plastic bags?
  • A:1) Different materials

    Biodegradable plastic bags (that is, environmentally friendly plastic bags) are made of PLA, PHAs, PBA, PBS and other polymer materials. The non-degradable traditional plastic bag is made of PE plastic.

    2) Different production standards

    Biodegradable plastic bags need to meet the national standard GB/T21661-2008, which has reached the environmental protection standard.

    The traditional non-degradable plastic bags do not need to comply with this standard.

    3) Different decomposition time

    Biodegradable plastic bags generally decompose within a year,

    while non-degradable plastic bags take 200 years to degrade.

  • Q:What are features of biodegradable materials?
  • A:1) It can be disposed of together with garbage, or made into compost to return to nature.
    2) The volume is reduced due to degradation and the service life of the landfill is prolonged.
    3) There is no problem that ordinary plastics need to be incinerated, which can inhibit the emission of harmful gases such as dioxin.
    4) It can reduce the harm of random discarding to wild animals and plants.
    5) It is convenient for storage and transportation, as long as it is kept dry, it does not need to be protected from light.
    6) Wide range of applications, not only can be used in agriculture and packaging industry, but also widely used in medical industry.
  • Q:Where are the main uses of biodegradable plastics?
  • A:There are two main areas for the use of degradable plastics.
    One is the area where ordinary plastics were originally used. In these fields, it is difficult to collect plastic products after use or consumption, which will cause harm to the environment, such as agricultural mulch and disposable plastic packaging.
    The second is the field of replacing other materials with plastic. The use of degradable plastics in these areas can bring convenience, such as ball tacks for golf courses, and seedling fixing materials for tropical rainforest afforestation. Specific applications are:
    1) Agriculture, forestry and fishery, plastic film, water-retaining materials, seedling pots, seedbeds, rope nets, slow-release materials for pesticides and agricultural fertilizers.
    2) Packaging industry, shopping bags, garbage bags, compost bags, disposable lunch boxes, instant noodle bowls, buffer packaging materials.
    3) Sporting goods, golf tacks and tees
    4) Hygiene products, women's hygiene products, baby diapers, medical mattresses, disposable haircuts.
    5) Medical materials, bandages, clips, small sticks for cotton swabs, gloves, drug release materials, as well as surgical sutures and fracture fixation materials.
  • Q:Do fully biodegradable plastics only degrade under composting conditions?
  • A:Composting is just one of the scenarios in which biodegradable plastics degrade.
    Most biodegradable plastics will degrade in natural environments such as soil, fresh water or seawater, and under suitable conditions of temperature and humidity, and will eventually be completely decomposed by microorganisms into environmentally harmless substances such as PBAT, PCL, PHA and other materials.
    Under normal circumstances, it can be completely degraded within six months at the earliest. PLA materials can also degrade in natural environments such as soil and seawater.
  • Q:Will 100% biodegradable plastics degrade during use?
  • A:No worries, it won't!
    The degradation conditions of degradable plastics include light, oxygen, heat, water, organisms and microorganisms and other factors, especially microorganisms are essential.
    In daily use these factors are not met at the same time, and therefore will not degrade.
    But biodegradable plastics have a shelf life. Please be aware and use them within their shelf life.
  • Q:What is the easiest way to test a bag real 100% biodegradable compostable?
  • A:Try lighting the bag in your hand, if the smell isn't too pungent, or even has a burnt popcorn smell, then it's a corn-based biodegradable compostable bag. 100% biodegradable compostable can be burn more compeletely.
  • Q:Do the material of the biodegradable bags all made of plant?
  • A:No. The material of the biodegradable made of mix PLA, PBAT and cornstarch.
  • Q:What is the load-bearing capacity of the biodegradable bag?
  • A:Usually, the load-bearing capacity of the bag depends on the thickness of the bag. Thicker bags can holder heavier items.
  • Q:Are biodegradable bags heat-resistant? What is the maximum temperature it can withstand?
  • A:No. Biodegradable bags are not heat-resistant. The maximum temperature it can withstand is around 80℃.
  • Q:How should degradable bags be stored?
  • A:It is recommended to store in a cool, dry place. Because biodegradable bags will degrade naturally in natural environments such as water, soil, and microorganisms. If the biodegradable bag is exposed to the natural environment and fully exposed to water, sunlight, soil, microorganisms, etc., it will accelerate its degradation, thus reducing the use time.
