    PP chemical name: polypropylene English name: (PP for short). The so -called PP bag is a plastic bag made of polypropylene as a material. It is generally used in color printing, plastic printing technology, bright color, and generally weave bags. kind. It is non -toxic, tasteless, smooth and transparent. It is easy to burn, the flame situation is melting, yellow and blue, less smoke after fire, and continues to burn. It is mostly used in the packaging of various industries such as cosmetics, food, toys, clothing, stationery, electronics, and hardware products. PP is a crystal -shaped high polymer. The PP in plastic is the lightest, and the density is only 0.91g/cm3 (smaller than water). In general plastic, the heat resistance of PP is the best, and its thermal deformation temperature is 80-100 ° C, which can be cooked in boiling water. The material of the material is transparent, excellent quality, and good toughness. Because of its hard and crisp material, it determines that it is only suitable for packaging and unsuitable bearing.
    but PP also has certain disadvantages: low size accuracy, insufficient rigidity, poor weather resistance, and "copper harm". It has a post -contraction phenomenon. After the mold is processed, it is easy to aging, brittle, and deformation.
    oPP chemical name: Direct polypropylene English name: Oriented (OPP for short), o is Oriented, the meaning of direction, two -way polypropylene (BOPP) is sometimes collectively referred to as OPP. OPP is a targeted stretch polypropylene film, which has the characteristics of high transparency and brittle. The folding side of the OPP single -sided side seal the edge of the side and the tongue of the open tongue has a self -stick seal. After folding your tongue, you can use it for easy use, beautiful and generous, and widely use in clothing, food, printing, stationery, cosmetics, paper and other industries. Various patterns and butterfly holes and airplane holes can also be printed according to customer needs.

The PP is the lightest in plastic, and the density is only 0.91g/cm3 (smaller than water). In general plastic, the heat resistance of PP is the best, and its thermal deformation temperature is 80-100 ° C, which can be cooked in boiling water. PP has a good resistance to crackedness, with high bending fatigue life, commonly known as "folding glue". The comprehensive performance of PP is better than PE material. PP products are light quality, good toughness, good chemical resistance. The disadvantages of PP: low size accuracy, insufficient rigidity, poor weathering, and "copper harm" easily. It has a post -contraction phenomenon. After the mold is removed, it is easy to aging, brittle, and deformation. In daily life, the commonly used fresh -keeping box is made of PP material. OPP is the directional polypropylene. O should mainly refer to the production process!
    opp: Direction, extended polypropylene, is a type of polypropylene
    and two -way polypropylene (BOPP)
    OPP Main Product:
    opP tape: with polypropylene film as a substrate material With the advantages of high -resistant tensile strength, light quality, non -toxic and tasteless, environmental protection, wide range of use, NOPP bottle: light weight, low cost, improved transparency, good heat resistance, suitable for heat irrigation. In recent years, the two -way polypropylene (OPP) transparent bottle has become the selection of the PET bottle

  3. wholesale diamond jewelry dallas OPP membranes have higher tensile stretching, tightness, transparency, gloss, printing performance, etc. than ordinary PP membranes, etc. The price is naturally higher, and the specifications are different. The sealing of the OPP membrane is more than double the traditional membrane, so that the moisturizing and freshness of its products are stronger, and the preservation time is longer.
    PP bag is a plastic bag made of polypropylene as a material. It is generally used in color printing, plastic printing technology, bright color, and generally weave bags. In addition One. It is non -toxic, tasteless, smooth and transparent. It is easy to burn, the flame situation is melting, yellow and blue, less smoke after fire, and continues to burn.

The color is transparent, excellent quality, and good toughness, because of its hard and crisp material, it determines that it is only suitable for packaging and unsuitable load.
    OPP is a targeted stretch polypropylene film, which has the characteristics of high transparency and brittle. The folding side of the OPP single -sided side is sealing the side and the tongue is sticking to the tongue. After the protective skin, the tongue can be folded firmly. It is convenient, beautiful and generous, and is widely used in clothing, food, printing, stationery, cosmetics, paper and other industries.

OPP rubber bag has crispy texture and high brightness. If there is no gap, it is difficult to tear, but there is a gap that you can tear it out without any strength. It is easy to explode when there is a problem with the raw material, or if there is a problem with the raw materials, but if the general items are not specially required, there are generally no problems. There are two forms of the sealing edge. , The other is to prevent explosion -proof edges. In fact, the two methods are the same when they are produced, but because of the positive and anti -knife, the process process of OPP rubber bags.
