For foam recycling, the code of expanded polystyrene foam (also named EPS or Styrofoam) is #6 in the plastic classification mark (a clockwise circular arrow forms a triangle number mark). All plastic products must be listed on the bottom or on the packaging, so that consumers and recyclers can sort it properly.

Foam #6 is often used to make various foam plastic products like protective material for disposable packaging in daily life due to its shock absorption, sound insulation and thermal insulation properties. In addition, in the field of food-grade packaging, foam has also overcome several technical difficulties and has become a popular disposable food container like food trays and foam cups in the market. Foam recycling makes the foam not only have its own use value for consumers, but also realizes the value of after completing its packaging mission.

Foam Packaging

Foam has excellent absorption of impact and vibration, and is usually used for cushioning and shockproof packaging, which can greatly reduce the damage of the product. In countries such as Europe and the United States, after delivering furniture, home appliances and some other products to the door, the merchant will take away waste foam packaging of the product; or, consumers will go to the store to pick up the goods and return home, and many foam packaging will be left after the demolition, which need to be recycled.

Foam Fish Boxes

The foam #6 is highly adaptable to changes in temperature and humidity. It has low water absorption, low hygroscopicity, and low thermal conductivity. It can be used in thermal insulation packaging such as fish boxes, to store and sell fish products, or for long-distance transportation of various fruits, the performance of foam packaging can bring us fresh ingredients, and it is not easy to expire after controlling the temperature.

Foam Medical Cooler

Medical coolers are usually made from foam #6 due to its good chemical stability, the foam itself will not corrode the contents, and it has strong resistance to chemicals such as acids and alkalis. Foam can maintain a stable critical temperature for medical supplies, provide insulation and help medications and vaccines be transported to hospitals and clinics around the world.

Foam Food Trays and Cups

For packaging materials, the requirements of food-grade are stricter. In the past, it was difficult to make foam #6 into a meal box, but now, with the continuous improvement of technology, the residue in the foam Toxic substances on the surface can be removed without releasing ingredients that are dangerous to human health, and food-grade foam #6 comes into being. Coffee cups, tea cups, and food trays made of foam on the market are increasingly favored by the market because of the low price and excellent thermal insulation performance.

Fabricated Foam

Global demand for foam products is so large which requires mass production of foam. In the production process of the foam itself, the large quantity of foam scraps are also the focus of foam recycling because finished foam needs to be cut and shaped according to different requirements. Effective foam recycling also can increase the value of foam, making it treasure instead of deserted trash.
