A lot of people in the purchase of packing belt will feel that the packing belt thick, better than the thin, this should be the most normal people's first sensory judgment, but the fact is not the case, packing belt manufacturers for you reveal such as identification of a packing belt is good or bad:
The quality of the packing belt is good or bad, depending on the purity of the polypropylene packing belt is not high, there are many kinds of packaging belt on the market: pure polypropylene, polypropylene
You pack
Add master stock, polypropylene plus recycled stock, polypropylene plus recycled stock and master stock. The packing belt produced by pure polypropylene is fully transparent, the packing ground produced by polypropylene plus master material is translucent, the packing belt produced by polypropylene plus recycled material is basically opaque, and the packing belt produced by polypropylene plus master material and recycled material is completely opaque. There is also a packaging belt produced by fully recycled material and calcium carbonate powder sandwich material. The packaging belt produced by completely recycled material is relatively soft. Only the surface of the belt of sandwich material is raw material, and the rest is calcium carbonate powder (lime powder). The quality of the packing belt completely depends on the purity of polypropylene, the higher the purity of polypropylene packing belt, the better the tension.
Joint mode of packing belt:
A) Hot melt lap type. It adopts heating methods such as electric heating welding, mechanical high frequency oscillation welding and ultrasonic welding. It is a way of bonding the plastic belt joint after the surface of the plastic belt is heated and melted, then the two melt surfaces of the belt end are lapped together and kept under a certain pressure for a certain period of time until the melting surface condenses. The joint mode is suitable for polypropylene plastic belt, because if the polypropylene plastic belt is mechanically fixed with iron buckle, its strength is only 50% of the base material, and the adhesive connection is not applicable.
B) Iron buckle type. This method is to use the one-way work of the ratchet of the tensioner to tensify the belt, and then place an iron buckle at the joint, and then make the iron buckle cover the two layers of belt with clamps, and the side teeth of the iron buckle are concave and convex tooth shape, and bite the belt will not cause its loosening. Iron buckle is usually made of galvanized iron sheet, the operation should be based on the strapping belt model to choose the appropriate specifications of iron buckle.
C) Ligation. This kind of joint is made of soft plastic rope, hemp rope and so on, and the joint is made into a slip knot. This joint mode is not only firm and beautiful, but also easy to untie.
The packing tape is made of a mixture of PP and PET plastics.
The main production process: plastic granule melt -- pressure belt -- molding -- cooling -- winding -- packaging -- warehousing packaging belt system using polypropylene through heating, melting, stretching, cooling produced by the network structure of packaging materials, the basic parameters affecting the quality of packaging belt are tensile force, length, bending, elongation, etc. As long as tension and other parameters are the same, the longer the length, the lower the cost.

Several commonly used packing belts:
You pack
Steel straps
It is generally used to make very heavy loads into one piece of transport or to fix loads in train cars, trailers or ocean cargo vessels. It is rarely used for contracted loads that have sunk or shifted after lashing, but it can be used firmly to tie compressed loads and is often used for rigid loads.
Nylon packing tape
With high continuous tension, it is generally used for heavy goods and contractive loads that can withstand high initial tension. Its elongation and recovery rate are greater than those of polyester or polypropylene strapping. It is the most expensive plastic strapping.
Polypropylene packing tape
It is the cheapest strapping material and is generally used for strapping, bundling and sealing cartons for lighter loads. Polypropylene packing tape has high elongation and recovery rate, but not as good as other plastic packing tape in terms of sustained tension.
Polyester packing tape
Highest strength and continuous tension in plastic packing tape. Polyester packing tape is an excellent strapping material for rigid loads that require constant strapping tension during loading, unloading, transportation, and storage. It is commonly used in applications requiring high tensile strength, high sustained tension and elongation. In many cases, its performance is similar to that of a lightweight specification steel packing belt.
PP packing tape
This product is used with automatic packaging machine, suitable for newspaper, publishing house, book office, paper mill, general merchandise, food, post office, confectionery, wood shop and so on.

Characteristics of PET packing tape

1. Strong tensile resistance:
2, the elongation is small: the elongation is only one sixth of the polypropylene (PP) belt, can maintain the tension for a long time.
3, strong temperature resistance: melting point of 260 degrees, 120 degrees below the use of no deformation.
4, good flexibility: no sharp edge of steel belt, safe operation, neither hurt hands nor damage the bundled objects.
5, beautiful not rust: no steel belt rust pollution is tied object, bright color can be seen.
6, good economic benefits: the length of 1 ton plastic steel belt is equivalent to 6 tons of steel belt, the unit price per meter is lower than the steel belt, can reduce the cost for you. |
