Whether the width of woven bag directly affects the bag-making process

YL PP/OPP WOVEN BAG, in the production process, it is necessary to pay attention to the amplitude design of the woven bag and the grasp of the feel problem, and the width of various woven fabrics directly affects the bag-making process. For the woven bag tube cloth, the width is expressed by bending, and the bending is equal to half the circumference. Width retraction rate, the width of all woven fabrics after weaving and rolling, after rolling cutting, printing, stitching, the width of the made bag should be slightly less than the width when rolling, we call width retraction.

In terms of the feel of woven bags, there are differences in the classification of different materials. PP flat woven fabric feel thicker, quite wide, rough and hard. HDPE flat woven fabrics feel soft, lubricated, not dense. Add calcium masterbatch to PP flat wire material, feel quite wide, PP less HDPE will make it softer. Flat wire is narrow, woven flat, soft feel, flat wire is wide, folding silk when weaving cloth, feel rough.

Woven bags should be stored in cool and clean indoor storage, transport should avoid the sun and rain, should not be near the heat source, storage period should not exceed 18 months. Because the plastic woven bag under sunlight is easy to age and shorten the service life, the experiment shows that the plastic woven bag in the natural environment, that is, under the condition of direct sunlight, its strength is reduced by 25% after a week, and it will be reduced by 40% after two weeks, basically can not be used.

That is to say, the storage of plastic woven bags is very important. In addition, after the plastic woven bag packaging cement is placed in the open environment under direct sunlight, the strength will drop sharply; Excessive temperature during storage and transportation (container transportation) or rain will cause its strength to decrease, thus failing to meet the quality requirements of the protection of the contents. Therefore, the transportation and storage conditions of plastic woven bags are very important.

What should be done with useless plastic woven bags? There are two main aspects to the treatment of waste woven bags, one is that we can recycle the waste woven bags back to the plastic woven bag manufacturer for recycling and processing, the two methods are to break the waste woven bags, and then bury them in the soil, so that it can be rapidly degraded, and the most important thing is that it will not cause any pollution to the environment.
