Material characteristics: Polyethylene is polymerized from ethylene and has the characteristics of being non-toxic, odorless, acid and alkali resistant, low temperature resistant, waterproof and insulating. It is widely used in the packaging field.
Classification and structure
Classified by material density:
High-pressure PE bag (LDPE): Made of low-density polyethylene, it is flexible and transparent, suitable for food preservation film, soft packaging, etc.
Low-pressure PE bag (HDPE): Made of high-density polyethylene, it has high hardness and strong puncture resistance, suitable for heavy object packaging or industrial use.
Recyclable PE bag: Made of recycled polyethylene (such as Recycled LDPE/HDPE), which conforms to the environmental protection trend.
Classified by use and process:
Flat bag: The bottom is sealed, the structure is simple, and it is used for packaging lightweight items.
Resealable bag/zip lock bag: With a reusable sealing strip, it is convenient for storing food or small items.
Anti-static PE bag: Anti-static masterbatch is added to protect electronic products from electrostatic damage.
Core characteristics
Safety:
Food-grade PE bags meet national standards (GB4806.7-2016), are non-toxic and odorless, and are suitable for room temperature food packaging.
Not suitable for high temperature (>110℃), high oil or frozen environments, as it may release harmful substances.
Physical properties:
Low-temperature resistant (-50℃ to 80℃), good chemical stability, but easy to age at high temperatures.
High-pressure PE bags have high toughness but low strength; low-pressure PE bags have high strength but poor ductility.
Environmental protection:
Recyclable PE materials support recycling, reducing resource waste.
Application scenarios
Food packaging:
LDPE cling film is used for preserving vegetables and meat; HDPE bags are used for loose food in supermarkets.
Industry and logistics:
Anti-static PE bags are used for packaging electronic components; HDPE heavy-duty bags are used for transporting machinery parts.
Daily life:
Resealable bags store jewelry and small items; flat bags are used for packaging clothing and daily necessities.
Keyword:
Cloth tape
It has the characteristics of flexibility, chemical corrosion resistance, and water resistance, and is widely used in packaging, agricultural covering, and industrial protection.
