In late December 2019, domestic customers consult our business manager about the jumbo bag and quickly confirm the order, customized products of different sizes.

After a period of production, the product was completed in mid-April.

Our innovative packaging increases loading and saves on shipping costs.

When the jumbo bag arrived at the customer’s company, the customer was very satisfied with our production process and production speed.

我们的 fibc bulk bags have been tested and proven to be superior in quality to general bulk bags.

We are also glad to have a quality customer.

The key reason for the broken edge of bulk bag sling is that the quality of sling is very poor. If it can’t stand too long-term application, it will break or break the edge, resulting in the problem that the overall container bag can’t be used.

Generally speaking, there are three reasons for the broken edge of sling:
A. excessive and frequent application and continuous lifting damage make the sling exceed the service life, and the similar container bags have already exceeded the service life or frequency, so new ones should be purchased.

B. the most important factor for the sling to rot is the poor quality of the sling made by the manufacturer. It can only be used once or twice. The bulk bag sling is rotten, but the overall body is not damaged. If it has the ability to repair, it can be removed and replaced.

C. another key element is that if incorrect materials are used to make a sling, it is the key problem that causes the broken edge of the bulk bag. If too much polypropylene is used and too little high-pressure polyethylene is used, it will cause the weathering layer. Because the container bag is often used outdoors, the broken edge is inevitable. If such a situation occurs, replace the manufacturer as soon as possible.

让我们详细讨论一下生产所用的材料 散装袋 in detail, as well as the physical properties and general chemical properties of various materials. Thank you.

What is the material of the bulk bag?

Two materials, polypropylene, polyethylene, polypropylene is a thermoplastic resin made by polymerization of propylene

Polypropylene is a non-toxic, odorless and tasteless milky white high crystalline polymer with a density of only 0.90 — “0.91g/cm3. It is one of the lightest plastics at present.

Polypropylene has good heat resistance. The products can be sterilized at a temperature above 100 ℃ and will not deform at 150 ℃ without external force. Due to the large shrinkage rate (1% ~ 2.5%), thick wall products are easy to sag, and it is difficult to meet the requirements for some parts with high dimensional accuracy and good surface gloss. It is very stable for water. Its water absorption is only 0.01%, and its molecular weight is about 80.15 million.

Polyethylene is generally a thermoplastic resin made of ethylene by polymerization.

Polyethylene is odorless, non-toxic, waxy and has excellent low-temperature resistance (the minimum operating temperature can reach – 100 ~ – 70 ° C). High-density polyethylene (HDPE) is commonly known as low-pressure polyethylene. Compared with LDPE and LLDPE, it has higher temperature resistance, oil resistance, steam permeability resistance and environmental stress cracking resistance. In addition, it has good electrical insulation, impact resistance, and cold resistance

Processing technology

Generally, these two kinds of raw material particles or powder are purchased in the production of the 散装袋. They are heated and stirred in the factory formula, drawn and shaped, then cut into the required raw silk, and then spun into the required or commonly used bulk bag base cloth by using a circular loom for standby

If you customize bulk bags, you can cut and sew these textiles forming base cloth into various specifications of the bulk bags. Generally, most of them are made of polypropylene. Occasionally, high-pressure polyethylene is used by companies that produce plastics or raw materials. The outer edge of bulk bag is generally coated with low-pressure polyethylene film to achieve the purpose of waterproof, so the basic material of the bulk bag is For those with these materials, it is generally necessary to add some other auxiliary materials to the ingredients in the production process.

In mid-October 2019, our foreign trade experts from Singapore consult with 1 ton of 散装袋 and quickly confirm the order with customized samples.

After factory design and production, the sample was shipped to Singapore in November.

upon arrival at the customer’s company, the customer is very satisfied with our production process and production speed.

我们的 FIBC bulk bags have been proven to outperform bulk bags in general. Customers quickly determine the order, and now the factory is in the midst of intense production.
We are also glad to have a quality customer.
