The structural formula for the chemical compound polythene is H(CH2CH2)nH. The CAS number for polythene is 9002-88-4. Polythene is another name for polyethene.
RO-CH2-CH2 + nCH2=CH2 ------ RO-(CH2-CH2)-CH2-CH2
Polythene is a polymer made from ethene.
Its structure is given below.

Polyethylene is a thermoplastic polymer.
- the polyethylene plastic bottle is unbreakable- the glass has a solubility (low and dependent on the type of glass) in acids
Polyethylene
The structural formula of 3-oxopentanal is CH3CH2CH2COCHO.
Polyethylene and polypropylene.
Polyethene seems to be a variant spelling of polyethylene, or polythene. I have include the Wikipedia link.
Polyethylene is a plastic, not metal. In fact, polyethylene is the most common plastic now-a-days.
Examples: polyethylene terephtalate (PET), polyethylene, polypropylene.
Polyethylene is a thermoplastic polymer.
CH3(CH2O)n is the formula for polyethylene oxide.
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).
No
polyethylene
Plastic polymer is comprises of about 70% of petrochemicals. The main byproducts of plastic polymers are High Density Polyethylene (HDPE), Low Density Polyethylene (LDPE), linear low-density polyethylene (LLDPE), PVC, Polystyrene and Polypropylene.

Formula: (C2H4)n
Plastic. Of course they're made out of plastic, The type of plastic is polyethylene. From the low melting point (195F) they are most likely made out of low density polyethylene.
