High density polyethylene foam. Use heat. Non foam plastic use super glue.

∙ 13y agoThe density of high molecular weight high density polyethylene (HMHDPE) typically ranges from 0.945 to 0.965 grams per cubic centimeter.
HDPE= High-density polyethylene
If you think to recycling codes: - 01 is for polyethylene terephtalate (PET) - 02 is for high density polyethylene (HDPE) - 03 is for polyvinyl chloride (PVC) - 04 is for low density polyethylene (LDPE) - 05is for polypropylene (PP)
Most of plastic bags are made of Polyethylene. It could be made of High Density Polyethylene (HDPE) or Low Density Polyethylene (LDPE) or a combination of both in addition to Linear Low Density Polyethylene (LLDPE).

LDPE is Low Density PolyEthylene.HDPE is High Density PolyEthylene.
High Density Polyethylene (HDPE)
HDPE is high density polyethylene used to make plastic pipe which is flexible, thermoplastic and non biodegradable. it is used in refineries for the transportation of water, gas, sewage etc.
One common way to separate PETE and HDPE is by using a sink-float separation method. Since HDPE is denser than water, it sinks, while PETE floats. This allows for the physical separation of the two plastics. Another method is by using automated sorting machines equipped with sensors that can differentiate between the two types of plastics based on their chemical composition or molecular structure.
High-density polyethylene (HDPE) has a higher density and stronger intermolecular forces, making it more rigid and resistant to heat and chemicals compared to low-density polyethylene (LDPE). LDPE is more flexible and has less strength and chemical resistance, but it is easier to process and has better impact resistance.
That's HIGH DENSITY, or HDPE in the plumbing business. Pro-Poly is one of the very few choices for this. The fact is that the group of olefins (polyethylene based plastics), which include LDPE, HDPE, and UHMW, are so chemical resistant that modern science has not invented a solvent glue to bond these plastics.
