纸塑复合袋 英文术语
Paper-plastic composite bags are widely ud in the packaging industry due to their excellent barrier properties, durability, and cost-effectiveness. The bags are made by combining multiple layers of paper and plastic, which provide enhanced strength, moisture resistance, and protection against contamination. In this article, we will discuss the technical terms associated with paper-plastic composite bags.
墨西哥世界杯1. Barrier properties: The effectiveness of a packaging material in preventing the entry or exit of gas, moisture, and other substances is known as the barrier properties. The barrier properties of a paper-plastic composite bag depend on the number and type of layers ud in the construction of the bag.
2. Lamination: The process of bonding two or more layers of materials together is called lamination. In paper-plastic composite bags, lamination is ud to join the paper and plastic layers.
raft3. Adhesive: The substance ud to bond two or more layers of material together is called adhesive. Depending on the type of paper-plastic composite bag, hot melt adhesives or water-bad adhesives can be ud.如何提高销售技巧

There are different grades of PE, including low-density polyethylene (LDPE) and high-density polyethylene (HDPE). LDPE offers high clarity and flexibility, while HDPE provides greater stiffness and strength.
5. Polypropylene (PP): Polypropylene is another common plastic ud in paper-plastic composite bags. PP has excellent barrier properties and is suitable for u in food packaging.

7. Ply: A ply refers to a layer of material, such as paper or plastic, in a paper-plastic composite bag. Depending on the bag’s requirements, multiple plies can be ud to achieve the desired strength and barrier properties.
8. Grammage: Grammage, also known as basis weight, is a measure of the weight of paper per unit area. Grammage is an important parameter in paper-plastic composite bags as it determines the strength and sturdiness of the bag.
9. Sack Kraft paper: Sack Kraft paper is a type of paper commonly ud in paper-plastic composite bags. Sack Kraft paper has high porosity, which makes it ideal for u in bags that require good breathability, such as tho ud for agricultural products.太傻网站
10. Co-extrusion: Co-extrusion is a process ud to produce multilayered plastic films with different properties. In paper-plastic composite bags, co-extruded films can be ud to achieve the desired barrier properties and strength.
11. Gust: A gust is a fold or pleat that allows a bag to expand or contract. In paper-plastic composite bags, a gust is ud to increa the bag’s overall capacity.日语能力测试报名
12. Valve: A valve is a special type of opening in a paper-plastic composite bag that allows air to be evacuated after the bag has been filled. This feature is commonly ud in bags that are ud to package powders, such as cement or flour.
In conclusion, paper-plastic composite bags are an important packaging material ud across various industries. Understanding the technical terms associated with the bags can help manufacturers and suppliers communicate better and ensure that the bags are produced to the desired specifications.模拟考>一桥大学
