What is the difference between BOPP synthetic paper and PE synthetic paper

There are significant differences between BOPP synthetic paper and PE synthetic paper in several aspects, and the following is a detailed analysis of these differences:

First, the raw materials are different

BOPP synthetic paper: polypropylene (PP) as the main raw material. Polypropylene is a thermoplastic resin with excellent mechanical properties and chemical stability. Through the bidirectional drawing process, polypropylene particles are processed into BOPP films with high transparency, gloss and mechanical strength, which can then be made into paper-like materials, namely BOPP synthetic paper.

PE synthetic paper: polyethylene (PE) as the main raw material. Polyethylene is also a thermoplastic resin, but compared with polypropylene, its molecular chain is softer, giving PE material good flexibility and low temperature resistance. PE synthetic paper is made using these characteristics of polyethylene through a specific production process.

Second, different performance characteristics

Properties BOPP synthetic paper PE synthetic paper

Transparency High transparency, good gloss transparency may be slightly lower than BOPP, but depends on the type of PE and production process

Mechanical strength has high tensile strength and tear strength mechanical strength is also good, but may be slightly worse than BOPP synthetic paper

Moisture resistance has good moisture resistance also has good moisture resistance, but the water resistance of the PE material itself may be better

Heat resistance The heat resistance is good, but the specific temperature resistance range depends on the additive and the formula has excellent low temperature resistance, but it may not be as stable as BOPP in high temperature environments

Chemical stability Good chemical stability, can resist the erosion of a variety of chemical substances also has good chemical stability

Easy to print, compound and die cutting and other subsequent processing performance is good, to meet a variety of printing and packaging needs

Third,Different application fields

BOPP synthetic paper: Because of its high transparency, gloss and mechanical strength, it is widely used in packaging, printing, labeling and other fields. Especially in product packaging that requires high definition printing and good appearance presentation, BOPP synthetic paper has significant advantages. In addition, BOPP synthetic paper can also be used to produce a variety of labels, advertising and other printed matter.

PE synthetic paper: It is more used in occasions that require flexibility, low temperature resistance and good moisture resistance. For example, in food packaging, pharmaceutical packaging and other fields, PE synthetic paper can effectively protect products from the influence of the external environment. At the same time, PE synthetic paper can also be used to make a variety of packaging bags, packaging films and other packaging materials.

Fourth, environmental protection

Both are environmentally friendly in that they can be produced using renewable resources and recycled materials. However, the specific environmental performance also needs to consider the energy consumption in the production process, emissions and recycling after waste treatment and other factors.

In summary, there are significant differences between BOPP synthetic paper and PE synthetic paper in terms of raw materials, performance characteristics, application fields and environmental protection. When choosing which synthetic paper to use, it is necessary to make comprehensive consideration according to the specific application requirements and scenarios.
