Have you ever noticed the plastic around you? They are usually printed with different symbols and numbers, most commonly, these symbols appear with numbers (1 to 7) to identify the type of plastic resin used in the product. For example, the number 1 corresponds to polyethylene terephthalate or PET - the material that water bottles are made of. Number 6 for foam cups and trays.



Do these numbers represent the recyclability of plastic? The answer is NO. These numbers and matches are more often just to tell you what the product is made of so that the user knows whether it can be used in food or whether it can be heated and so on. But these numbers don't mean much when it comes to recycling.



Foam usually refers to polystyrene or Styrofoam. Two types of foam recycling machines commonly are foam densifiers and foam compactors. But with the change in the market, more and more rigid plastics also need to be recycled, at this time GREENMAX foam crusher series has become the new choice of rigid plastics recycling.



The treatment principle of foam compression is to squeeze out the excess air in the foam so as to reduce the foam volume and facilitate the subsequent operation of other steps of foam recycling. But for some hard plastics such as HDPE, PU, and other materials, crushing treatment may be better. GREENMAX foam crushers have also become the top choice for these rigid plastic recyclers, and more often they choose to use a cleaning or pelleting line to convert scrap to marketable pellets. A new way of recycling foam crusher has been developed instead of the previous extrusion treatment model.



The way plastic foam and other hard rigid plastic are recycled is being reinvented by foam crushers, and the kind of foam that few people are willing to recycle is now taking a new direction. The foam recycling market is changing all the time, and Ingroup is changing itself all the time. We are constantly introducing new products to improve the foam recycling problem.
