PP packing belt is a commonly used material in logistics, mainly used for packaging packaging. PP packing belt with high performance, high tensile strength, can ensure that the load is strong enough, tension relaxation is small, combined to ensure that the long-term not loose. Today, I'm going to talk to you about regular plastic bags.
How to choose the material of PP packing belt
The connection method of plastic packing belt usually has three kinds: hot melt method, clasp ring method and binding method. Manual packing belt is mainly for ordinary dimensional accuracy requirements, baler strength requirements are ordinary, can choose waste plastic production, appropriate to add some fillers. The dip Angle can also be slightly higher, the general thickness is below.3 mm, the width is about 5-25 mm, and the commonly used method is the fastening connection.
PP packing belt with the main dimensional accuracy and strength is very high, small deflection, and hardness, size thickness is generally mm, width of about 3 mm, often use hot melt and method connection, and the choice of raw materials is not suitable for more packaging, baler thickness can not be too thick, in case of hot melt temperature is too high.
The production process of PP packing belt is generally as follows: extrusion - cooling - one hot drawing - hot setting treatment - two hot drawing - hot setting treatment - product.
Packaging tape commonly used in the production of plastic raw materials: PP, HDPE, PVC, PET and nylon, etc., most of the PP polypropylene resin has been used at present. The dose is more than 90%.
The following are the main advantages of polypropylene resins. The typical formula of PP packing belt is all polymer, PP waste can also be selected through artificial packing belt, calcium carbonate as packing choice, baler can add light stabilizer for outdoor packing belt.
Here are two recipes for reference only.
1.PP packing tape. PP particles,PP powder,APP masterbatch 5%, casting 0.2%, triphenyl phosphate 0.2%, white oil 0.2%, which are important components.
2.PP artificial packaging waste PP, casting 0.5%,APP main material 90%, white oil 0.2%. Handband can also be used as waste woven bag PP material production. |
