30*54cm PP Woven Bag for rice can be loaded 5kg
- Definition and raw materials
Definition: Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging.
Raw materials: Generally various chemical plastic raw materials such as polyethylene and polypropylene.
2.Production process
Woven bags are made of chemical plastics as the main raw materials, which are extruded and stretched into flat wires, and then woven, knitted and made into bags.
3.Features
Advantages: It has high tensile strength, wear resistance and corrosion resistance; the surface has good waterproof and moisture-proof properties after treatment; Woven bags made of plastic raw materials such as polypropylene can be recycled and meet environmental protection requirements; the production cost is low and the service life is long; the use of a woven structure design with strong air permeability helps to remove moisture from the inside of the package; it has strong load-bearing capacity and is not easy to break or leak.
Disadvantages: There is a certain gap between the warp and weft, and the puncture resistance is poor; if there is no additional moisture-proof measure inside, its moisture-proof and humidity-proof properties may not be ideal; it may become brittle in low temperature environments and have poor low temperature impact resistance; long-term exposure to sunlight or high temperature environments may accelerate aging.
4.About Printing
• High printing precision: It can clearly present fine patterns and texts, and has a high degree of reproduction of trademarks, complex patterns, etc. The printed lines are delicate and the color transition is natural.
• Rich color expression: Using CMYK four-color printing or more spot color printing, it can accurately reproduce various colors, with bright colors and high saturation, which can meet the needs of customers with high color requirements.
• Fast printing speed: It is suitable for mass production and can complete the printing tasks of a large number of woven bags in a short time, improving production efficiency.
• Low printing cost: When printing in large quantities, the unit printing cost is relatively low, which has good economy.
5.Application areas
• Food packaging: such as rice, flour, feed and other packaging bags, offset printing can make the brand logo, product information, etc. on the packaging clearer and more beautiful, attracting consumers.
• Chemical product packaging: used to package chemical products such as fertilizers, cement, putty powder, etc., the printed product name, instructions for use and other information are accurate and clear, convenient for users to use.
• Logistics packaging: In logistics transportation, offset printed woven bags can be used to package various items, and printed logistics logos, barcodes, etc. are helpful for logistics management and cargo identification.
