Since its inception, plastics have been widely used in various fields of the national economy, such as the packaging industry and the disposable product industry, bringing great convenience to human production and life. However, The world already produces more than 8 billion tons of plastic, its huge use and waste have led to increasingly serious environmental pollution - "white" pollution, including river pollution, farmland mulch pollution and marine plastic pollution. 9% of it is recycled and 90% is landfilled, incinerated and thrown into the sea. As we all know, burning plastics will cause air pollution and environmental damage. Traditional plastics need to be degraded in 500-800 years by landfilling, which will waste the world's land resources.
Governments and industries propose: replace traditional plastics with "degradable plastics".Plastics also need "sustainable development".Protecting the earth is an eternal topic. Goolien Packing Technology Co., Ltd. keeps up with the pace of world development. We are committed to researching and developing various environmentally friendly materials, developing new products, and eliminating white pollution.We are the production and solution provider of biodegradable raw materials and products.Goolien will do its best to contribute to the cause of environmental protection and give full play to our social responsibilities.
Global-Recycled-Standard
The Global Recycled Standard (GRS) is an international, voluntary, full product standard that sets requirements for third-party certification of Recycled Content, chain of custody, social and environmental practices, and chemical restrictions. The goal of the GRS is to increase use of Recycled materials in products and reduce/eliminate the harm caused by its production.The objectives of the GRS are:
1 Track and trace Recycled input materials.
2 Provide customers (both brands and consumers) with a tool to make informed decisions.
3 Reduce harmful impact of production to people and the environment.
4 Provide assurance that materials in the final product are actually Recycled and processed more sustainably.

D2W™
D2W™ grade 93389/C is an oxo-biodegradable additive based on a polyethylene carrier resin formulated for demanding processing application requiring a high degree of thermal stability, D2W appears as light brown particles.Under normal storage conditions the product has a shelf life of 18 months from the date of manufacture which is printed on the sack.D2W is an additive formulation that renders conventional polyolefins oxo-biodegradable.“OXO-biodegradation” is “degradation identified as resulting from oxidative and cell-mediated phenomena, either simultaneously or successively.”D2W oxo-biodegradable plastics are not currently intended for composting.If sent to landfill d 2 w oxo-biodegradable plastics will degrade in aerobic conditions. In anaerobic conditions they become inert and will not emit methane.

Ecopure
ECO are a class of plastics that degrade due to the action of naturally occurring microorganisms such as bacteria, molds (fungi) and algae.Features of ECO material:
1 With the addition of ECO, the plastic is biodegradable through anaerobic digestion in landfills and decomposes naturally in household composting. Tested according to ASTM D5511.
2 Clean and renewable energy: only water, carbon dioxide, bath gas and biomass (humus) are produced during the decomposition process. Tested according to ASTM D5511.
2 Clean and renewable energy: only water, carbon dioxide, bath gas and biomass (humus) are produced during the decomposition process. Tested according to ASTM D5511.
3 Clean and safe: 1-5 years biodegradation, no residue after biodegradation, like organic, microorganisms will continue to eat ECO treated plastic until it is not consumed, the rest of the materials are natural. Tested and passed ASTM E1963 BDP, it simply enhances natural processes by allowing microorganisms to enter the polymer chain.No change to the original physical properties of the plastic, the product can be recycled and reused without landfill, and the use time is long.

Polylactic acid (PLA)
Polylactic acid is a biodegradable polymer produced from renewable resources such as grains.Traditional lactic acid fermentation mostly uses starchy raw materials. Used agricultural and sideline products such as corn, sugar cane, sugar beet, and potatoes as raw materials to ferment lactic acid, and then produce polylactic acid. Corn is the preferred raw material for the biodegradable plastic polylactic acid.Because lactic acid and lactide contain asymmetric carbon atoms, PLA with different stereoregularities, such as L-PLA, D-PLA and DL-PLA, can be obtained by polymerization. The degradation of PLA is divided into two stages:
1) First, it is pure chemical hydrolysis to lactic acid monomer;
2) The lactic acid monomer is degraded into carbon dioxide and water under the action of microorganisms. The food cup made of polylactic acid can be completely degraded in only 60 days, which truly achieves the dual effect of ecology and economy.
