Differences between PET and APET plastic sheet roll

Both PET and APET are the most common plastic films in the material packaging industry. They differ in terms of material cost and surface treatment, transparency, optical properties, melting point and application areas, etc. The following is a detailed description of their differences.


What are their differences?

PET plastic sheet:

PET plastic sheet roll is composed of polyethylene terephthalate, which usually requires a corona treatment to increase its surface tension for subsequent printing and coating. PET may not have the same transparency and optical properties as APET, PET does not have a high melting point and does not require very high temperatures for processing. PET can be used in the production of caps for mineral water bottles, printing, packaging, etc.

APET plastic sheet:

APET is made of amorphous polyester and does not require surface treatment, as there is sufficient tension on the surface. It has good optical properties and transparency, so it is more suitable for food packaging, electronics packaging, cosmetic containers, cards and other applications that require more plastic film.

Therefore, APET is more popular than PET, but both materials can be used for recycling, because they can be recycled and reprocessed, and the recycled material can be re-produced into new plastic products, which helps to reduce the amount of waste disposal and reduce environmental pollution problems. Although there are differences between these two materials, they both have a wide range of application prospects and important economic value, but also need to choose the right material for proper production and processing, in order to maximize their characteristics and benefits and contribute to environmental protection.
