Factors affecting the tightness of plastic drums

- Nov 14, 2019-

1. The plastic material is not good. Usually, some manufacturers do not mix waste materials to reduce the cost of products, which leads to a decline in the quality of raw materials, thus affecting the sealing of plastic drums;

2, the material formula is not professional. There are many kinds of materials for producing chemical plastic barrels. The commonly used materials are polyethylene and polypropylene. The plastics and additives used in the production of chemical plastic barrels are different, and the properties of different raw materials are quite different. Some materials are hard, some materials It is softer, and to improve the sealing performance of plastic drums, it is necessary to fully understand the material properties and give full play to its advantages. The proportion and formulation of materials are critical, which is an important factor affecting the tightness of plastic drums;

3, the mold is not precise enough. The lack of precision of the mold will affect the fit of the plastic lid and the barrel. The precision of the mold is also an important factor affecting the sealing of the chemical plastic barrel;

4. The equipment has not been debugged. The equipment must be commissioned before production. The poor commissioning will also affect the sealing of chemical plastic drums.https://www.fhpails.com/
