At present, plastic woven bags of plastic woven bags manufacturers are mainly exported to Japan and South Korea, and are vigorously developing markets in the Middle East, Africa, the United States and Europe. Due to the production of oil and cement, the Middle East has a great demand for plastic woven bag products; in Africa, almost all of its state-owned oil companies focus on the development of plastic woven products, and the demand for plastic woven bags is also very large. Africa can accept the quality and grade of Chinese plastic woven bags, so there is no big problem in opening the market in Africa. The United States and Europe have high requirements for the quality of plastic woven bags, and China's plastic woven bags have not yet met their requirements.
The design of plastic woven bag manufacturers must strictly implement the national standard GB/T10454-2000. Plastic woven bags are used as export packaging to ensure that the exported goods effectively protect the loaded items during loading, unloading, transportation and storage, and transport the goods to their destinations in a safe and intact manner. Therefore, the design of plastic woven bags must meet four main points, namely safety, storage, usability, and sealing.
Mainly refers to the strength of plastic woven bags. In the design, we must consider the packaging volume, the weight of the load and the packaging unit (number), also consider the distance of the transportation distance and the number of times of transportation, what operating tools and transportation methods are used. In GB/T10454-2000 National Standards for Plastic Woven Bags, the technical specifications of plastic woven bag base cloth and slings are strictly stipulated. From a safety perspective, it is clear that all plastic woven bag structures are bottom hanging structures. The safety factor must be 1:6.
According to the user's conditions of use, reasonable selection of materials and reasonable ratio. The anti-aging ability of plastic products under sun exposure is a problem that is currently more concerned, and it is also a problem often encountered in the actual use of plastic woven bags. Pay attention to the use of anti-violet agents and the selection of materials during the production process.
When designing plastic woven bags, we must fully consider the specific ways and methods for customers to use plastic woven bags, such as lifting, transportation, and loading material performance. In addition, it is necessary to consider whether it is food packaging, and it is necessary to consider non-toxic and harmless to the packaged food.
Different packaging materials require different sealing requirements. Plastic woven bags such as powder or toxic items, and items that are afraid of being contaminated have very strict requirements for sealing performance. Materials that are prone to moisture or mildew also have special requirements for air tightness. Therefore, when designing plastic woven bags, pay attention to the influence of the base fabric coating process and the sewing process on the sealing.
The specific features are as follows:
1. The load capacity of the plastic woven bag is between 0.5-3T, and the volume is between 500-2300L. The insurance factor can be designed according to user needs 3:1, 5:1, 6:1.
2. According to the content, the goods are divided into bulk plastic woven bags and small package plastic woven bags, which are suitable for one-time use and revolving use.
The quality of plastic woven bags is good or bad, it is crucial. Therefore, there are strict standards for plastic woven bags on the international market. The emphasis of the standards varies. Japan pays attention to details, Australia pays attention to form, and the European Community standards focus on product performance and technical indicators, which are concise and concise. The United States and Europe have strict requirements for plastic woven bags in terms of anti-purple thread, anti-aging, and safety factor.
