Polyethylene sheet (PE sheet) does not contain formaldehyde and is a non-toxic and environmentally friendly material. According to the professional description in the search results:
Material characteristics
The main component of PE sheet is polyethylene, and this high molecular polymer does not require the addition of formaldehyde during the manufacturing process. The search results clearly state: "PE sheet (polyethylene sheet) also does not contain formaldehyde", and Baidu Encyclopedia also describes it as a "non-toxic" material.
Application areas
Its formaldehyde-free characteristics make it widely used in food packaging, medical equipment (such as aquariums, chemical containers) and other fields with high environmental protection requirements.
Comparison with other materials
PVC sheet: Some PVC sheets may contain formaldehyde due to additives (such as urea-formaldehyde resin in plastic wall panels), but ordinary PVC sheets may also be formaldehyde-free under vacuum technology.
PP sheet: Similar to PE sheet, it is also an environmentally friendly plastic that does not contain formaldehyde.
Suggestion: When purchasing, you still need to pay attention to whether the product has passed the environmental certification to avoid adding other harmful substances to inferior materials. If you want to learn more about the safety of plastic products, you can study polypropylene sheets or environmentally friendly plastic certification standards.
