Recycled material packing belts are usually divided into three types: core-spun belts, calcium carbonate packing belts, and all-plastic packing belts. The three kinds of packing belts have similar appearances. How to distinguish them? The packing tape manufacturer will tell you how to distinguish the three in popular science.

How to distinguish between core-spun strap, calcium carbonate strap, and all-plastic strap:

Combustion method:

Burn these three different straps with fire, then observe their flames and their respective odors, and finally observe the burning material. The following is their performance in various situations.
The flame smoke generated during the core-spun belt burning process is thick and produces a strong pungent odor. The burning material left after full burning is mostly white powder, and the burning material has no plastic linear characteristics, and cannot be drawn. It is from the proportion of white powder. It can be seen that the proportion of impurities is quite large.Calcium carbonate packing belt also produces smoke during the burning process, which is smaller than the core belt. The burning material left after full combustion also has white powder, and the burning material has no plastic linear characteristics and cannot be drawn. It can be seen from the proportion of white powder. Its composition also contains impurities, and the proportion of impurities is less than that of the pericardium.The flame is bright during the burning process of the all-plastic strapping belt, no obvious smoke, no strong pungent odor, and a faint petroleum odor. The burning products left after full combustion are free of foreign matter and impurities, and they are all crystalline transparent solids. Shows the linear characteristics of plastic and can be drawn.

Appearance method:

If the conditions do not allow burning, the appearance method can also be used to make a preliminary judgment. The specific method is as follows:
Tear the core-wrap tape, and wrap most of the lime powder core (lime powder or calcium carbonate powder) in the thin plastic layer. The tearing opening is wireless performance, and the tearing opening is uneven, and the strapping is bent by hand , Its recovery performance is poor, the hardness is small, this belt is the lowest grade packing belt. The ratio of plastic raw materials to calcium carbonate content is about 30%:70%, and the cost of raw materials is low.
The tear surface of the calcium carbonate strapping belt has no obvious impurities, and the tear opening has a better linear performance relative to the core belt. Compared with the tear opening of the core belt, it is more tidy. The strap is bent by hand, and its recovery performance is better. The heart belt is slightly stronger and harder. The quality of this belt is slightly higher than that of the core belt. The ratio of plastic and carbonic acid powder in it is about 60%:40%, and the cost of raw materials is relatively low.
The linear performance of the tearing of the all-plastic strapping is good, the tearing is neat and uniform and no impurities are seen. The strapping is bent by hand, its recovery performance is excellent, and the hardness is strong. This strapping is a high-grade strapping, and its material is 100% plastic raw materials.

Proportion Method:

This method uses the principle that PP plastic has a lighter specific gravity than water and floats in water to do this experiment, and cut a small section of the strap into the water. PP all-plastic strapping is made of 100% all plastic, and its specific gravity is lighter than water, so it floats on water. Carbonated strapping and core-packing straps contain calcium carbonate impurities, which make their specific gravity heavier than water. Therefore, both the nucleus belt and the carbonated belt are submerged in water, so the approximate ratio of the plastic content in the packing belt can be actually identified.

The above is the differentiation method of core-spun tape, calcium carbonate packing tape, and all-plastic packing tape.
