The problems of inferior cement packaging bags are as follows: 1. Package breakage and leakage In addition to gravity, cement is often subjected to various external forces during loading, unloading and transportation. Most of these forces are borne by the packaging bags, so the packaging bags are required to have the ability to make the packaging bags resistant to damage during normal handling, loading, unloading and transportation of cement. However, in the actual transportation process, it often happens that the package is broken or missing. On the one hand, this situation is caused by the excessive addition of recycled materials and recycled materials in the production process of the bag-making enterprises in order to reduce costs; On the other hand, it is due to the backward production equipment and technology of bag making enterprises and the poor weaving technology. 2. Punching problem When packing cement, the cement factory requires that the cement packaging bag have certain permeability. Therefore, paper bags, laminated plastic woven bags and other types of composite bags need to be punched before leaving the factory. Large pore size, large number of holes, good exhaust performance, high filling efficiency, but serious leakage of cement during filling, poor moisture resistance; The hole diameter is small, the number of holes is small, the exhaust performance is poor, and the filling efficiency is low. However, when filling, the cement escapes less, and the moisture resistance is good. Therefore, the size and density of the needle hole are the key factors that affect the phenomenon of cement leakage and ash emission and the moisture resistance of cement during filling. However, most bag-making enterprises and cement enterprises only focus on the filling efficiency, but neglect the moisture-proof performance of cement packaging bags. 3. Moisture prevention It is easy for cement to absorb moisture in the air, and hydration will occur and coagulate into blocks, thus losing the cementation ability. Therefore, moisture-proof performance is one of the important indicators to determine whether the cement packaging bag is qualified. However, due to the fact that cement bag manufacturers cut corners in the production process, the density of warp and weft is sparse, the lamination film is too thin, the adhesive strength is not enough, the perforation needle hole is too large or the perforation density is too large, resulting in the overall low moisture resistance index of cement packaging bags in China. The sampling results of the regulatory agency show that the moisture-proof performance is the main factor leading to the appearance of unqualified products in cement packaging bags. 4. Appearance and printing problems It is specified that the appearance of the cement packaging bag shall be flat, free of cracks, degumming and sticking, and the printing shall be clear and complete. The integrity of the information of the cement packaging bag is to ensure the correct use of the cement packaging bag by the customer, and it is also the necessary information for the quality inspection agency to inspect the packaging bag.

Cement packaging bags are mainly used for the quality protection of cement. Because of the hygroscopic and deliquescent properties of cement, it is necessary to effectively protect the cement in the form of packaging in order to avoid the change or reduction of cement quality efficiency in storage, transportation and storage, or to maximize the function of cement. It can be said that cement packaging bags participate in the whole production, packaging, storage and transportation, marketing and other links of cement, and are also an integral part of cement quality production. Inspection items of cement packaging bags The requirements for the test items of cement packaging bags are mainly focused on the "bag making materials" in Chapter IV and the "technical requirements" in Chapter V. The basic requirement of "bag making material" is that it must have no impact on cement performance and meet the requirements of relevant standards. 1. Recommended test items for paper bag paper: quantitative analysis, quantitative deviation analysis, quantitative difference analysis of banner, tear index measurement, permeability measurement, water absorption performance measurement, tensile index measurement, elongation measurement, tensile capacity absorption index measurement, exchange moisture measurement, etc; 2. Recommended test items for stretch paper bag: quantitative analysis, quantitative difference analysis of banner, tear index measurement, permeability measurement, water absorption performance measurement, tensile index measurement, elongation measurement, tensile capacity absorption index measurement, exchange moisture measurement, etc; 3. Recommended test items for plastic woven bags: appearance defect analysis, allowable deviation test, tensile load test, peeling force test, heat resistance test, drop solubility test, UV resistance test, etc.
