I just searched it roughly and saw PP strapping, PET plastic steel strapping, environmental protection strapping and so on. I would like to ask if we usually use PP packing tape? Or what is the difference between the above packing belts? What are the raw materials used in the production of strapping (new materials and recycled materials)? If you want to introduce equipment, where can the equipment be relatively inexpensive and good-quality? Ha ha! Please enlighten me, thank you! (Alibaba Rubber and Plastic Forum author njdan)
Netizens send at one point: 1: Most of the straps on the market are PP straps.
Two: PP and PET have different uses. PP strapping has wide applicability, easy heat sealing, low specific gravity and low cost. The heat sealing temperature of PET strapping is high, and the specific use cost is high. The environmentally friendly packaging belt is just a propaganda by the business, and it has no practical significance.
3: The processing materials of PP strapping are polypropylene raw materials or recycled materials, and the two can also be mixed. The material used for PET strapping is generally recycled PET bottle flakes or PET recycled viscosity-increasing pellets.
Four: PP strapping machine, the low price uses Shandong's 20,000-30,000/unit, and the high-end uses Korean Dacheng or Japan. If you are in the mid-range, please contact me.
Netizen 2 Shanghai Aaron: PP straps are mostly used in the market
Netizen 3 Tearsless Confession: It is usually made of PP, and it is usually made of recycled materials. Polypropylene use:
(1) Film products: polypropylene film products are transparent and shiny, and have little permeability to water vapor and air. They are divided into blown film, cast film (CPP), biaxially oriented film (BOPP), etc.
(2) Injection molding products: can be used for engineering accessories such as automobiles, electrical, machinery, meters, radios, textiles, national defense, daily necessities, turnover boxes, medical and health equipment, and building materials.
(3) Extruded products: can be used as pipes, profiles, monofilaments, fishing ropes. Packing straps, strapping ropes, woven bags, fibers, composite coatings, sheets, plates, etc. Blow-molded hollow molded products, various small containers, etc.
If you want to inquire about the equipment, you can go to the Machinery Equipment Forum, where there are experts.
(4) Other: low foaming, calcium plastic board, synthetic wood, laminate, synthetic paper, high foaming can be used as structural foam.
