Q:What material is the packing belt made of?

Polypropylene is a thermoplastic resin made by the polymerization of propylene. According to the location of the methyl group into isotactic polypropylene (isotactic, polyprolene), random polypropylene (atactic polypropylene) and syndiotactic polypropylene (syndiotactic, polypropylene) three kinds.The arrangement of methyl groups on the same side of the molecular backbone is called isotactic polypropylene. If the methyl group is arranged in random order on both sides of the backbone, it is called atactic polypropylene, and when the methyl group is arranged alternately on both sides of the backbone, syndiotactic polypropylene is called. In general industrial polypropylene resins, the isotactic structure is about 95% and the remainder is atactic or syndiotactic polypropylene. Industrial products are based on isotactic substances. Polypropylene also includes copolymers of propylene with a small amount of ethylene. Usually translucent, colorless solid, odorless, non-toxic. The melting point can be as high as 167 DEG C because of the highly crystalline structure. Heat resistance and corrosion resistance, products can be steam disinfection is its outstanding advantages. Small density, is the lightest general plastic. The disadvantages are low temperature resistance, low impact and easy aging, but can be overcome by modification.

Q:What is the standard of plastic strapping?

Characteristic(1) strong tensile resistance, both tensile resistance of the steel band, but also the ductility of the impact resistance, but also to ensure the safety of transport products.(2) the elongation is small, the elongation is only 1/6 of the polypropylene band. It can keep the tension for a long time.(3) strong heat resistance, melting point of 260 degrees, 120 degrees below using deformation.(4) good safety, no steel belt rust, contamination of tied objects, bright colors.

Q:What adhesive tape do you use?

Common polyethylene, polypropylene resin as the main raw material, but also to nylon and polyester, polyester and the tensile strength of nylon strap, and polyethylene and polypropylene strapping polypropylene with low cost, good elasticity, can be selected according to different material strapping needs. ;

Q:What is the reason that the packing machine can not be put in?

Tighten wheel belt did not stir, blocking the slip past

Q:What's the difference between hand packed belts and machine packs?

Generally, there is no paper ring for hand packing belt, and belt for machine must be paper ring;

Q:What is the reason why the packing belt breaks easily?

For a long time, and do not pay attention to cleaning, resulting in packaging machine hot tongue on the dirt is too much, as long as sandpaper is used to rub off the stain on it;3, semi automatic packing automatic packing machine or the hot side, packaged hot melt zone is too small, the use of pliers correction;

Q:How many meters is one ton of packing belt?

There are many kinds of packing tape, different materials, usually 10 kilograms per roll, and the number of meters per roll is also different,

Q:What are the classification of the packing belt?

That's a lot of sorting. According to what parameter you want to divide.Generally have PP packaging belt, PET packaging belt.Machine packing belt and hand packing beltNew material packing belt and feed back packing belt.Also transparent and opaque. Having or having no color. Wait

Q:Do you need a packing belt for the airport consignment bag?

If your bags are intact, no packing straps are required. They are usually packed in flimsy cartons or bags

Q:How to identify the quality of a packaging belt?

1, smell: use lighter ignited 3 seconds after blow out, the smell of it, identify it and new material PP difference, one should note that some color toner, smell great, will cover PP (PP renewable materials) part of the taste, don't worry, there's another way.2, color law: every belt is better than impenetrable, no matter what color.3, look shiny: gloss better than no gloss, gloss is the so-called material itself has, just as the same color, the color of the surface material is.
