The characteristic advantages of kraft paper composite bags are mainly reflected in the following aspects:
1. Excellent physical properties
*Resistant to stretching, compression, abrasion and folding: Kraft paper composite bag combines the strength of kraft paper and the toughness of plastic film, which makes it have good physical properties, able to withstand greater weight and pressure, to protect the contents from damage.
*Good sealing performance: through heat sealing or other sealing methods, kraft laminated bags can provide good sealing effect, preventing the entry of external impurities, while maintaining the freshness and dryness of the items inside the bag.
2.Outstanding protection
*Moisture-proof and waterproof: the plastic film layer can effectively isolate moisture and prevent the contents of the bag from getting wet. This is especially important for items that need moisture protection, such as food and medicine.
*Barrier gas: kraft paper composite bags can also block oxygen and other gases to a certain extent, slowing down the rate of oxidation of the items, prolonging the shelf life.
3.Eco-friendly and biodegradable
*Eco-friendly material: Kraft paper is a biodegradable material, which can be naturally decomposed or recycled after use to reduce pollution to the environment. This is in line with the current global advocacy of environmental protection concept.
*Reduce the use of plastic: compared with traditional plastic bags, kraft paper composite bags to a certain extent to reduce the use of plastic, help reduce plastic pollution.
4.Printing adaptability
*Flat and smooth surface: the surface of kraft paper composite bags is flat and smooth, which is conducive to various printing processes. Whether it is intaglio printing, screen printing or flexographic printing, etc., it can present clear and bright patterns and text on its surface.
*Enhance the aesthetics: good printing adaptability makes kraft paper composite bags not only practical, but also has a high degree of aesthetics, which helps to enhance the competitiveness of the product market.
5.Cost-effective
*Cost-effective: although kraft paper laminated bags are superior to some traditional packaging materials in terms of performance, their relatively low cost can meet the packaging needs of most enterprises. This makes it widely used in companies seeking cost-effectiveness.
*Wide application: due to its excellent performance and low cost, kraft paper laminated bags are widely used in many fields such as food, industry, agriculture, chemical industry and so on. Whether it is to carry heavy loads or to protect fragile goods, it can excel.
In summary, kraft paper composite bags have become an important member of the modern packaging industry with its excellent physical properties, outstanding protective properties, environmental protection and biodegradable features, as well as good printing adaptability and cost-effectiveness. With the increasing awareness of environmental protection and the continuous progress of science and technology, I believe that the kraft paper composite bags in the future application prospects will be more broad.
