Compared with other paper food bags, Kraft Paper Bag shows significant advantages in strength and toughness.
1. Strength of Kraft Paper Bag
Physical strength: Kraft paper is about 1.5 times stronger than ordinary paper. This high strength makes the kraft paper bag more stable and not easy to break when carrying heavy objects. For example, a four-layer stretch kraft paper bag filled with 25kg of flour can still keep the packaging intact after 10 free falls from a height of 1.2 meters, which fully proves its excellent physical strength.
Load-bearing capacity: Kraft Paper Bag can withstand high-intensity use environments without being easily deformed. Its light and tough paper allows it to maintain the integrity of the bag shape when loading heavy objects, effectively protecting the safety of the food in the bag.
2. Toughness of Kraft Paper Bag
Tear resistance: Kraft Paper Bag has good tear resistance and can withstand friction and impact during various transportation and handling processes, and is not easy to be torn. This toughness ensures the safety of food during transportation and storage, and reduces losses caused by packaging damage.
Durability: Due to the high strength and toughness of kraft paper bags, it is more durable during use. Even after multiple uses and repeated folding, its shape and performance can remain relatively stable, extending its service life.
3. Comparison with other paper food bags
White board paper: White board paper is a relatively cheap paper, but its strength and whiteness are also average, and it is gray inside. Although it is suitable for some ordinary items, it is obviously not as good as kraft paper in carrying heavy objects and resisting tearing.
White cardboard: The strength and toughness of handbags made of white cardboard are OK, but the cost is generally high. In contrast, Kraft Paper Bag has cost advantages while maintaining good strength and toughness.
Coated paper: Paper bags made of coated paper are very hard, with bright colors and good saturation, but they are mainly used in fields such as printing and packaging decoration, and their toughness and durability may not be as good as Kraft Paper Bag.
In summary, Kraft Paper Bag is superior to other common paper food bags in terms of strength and toughness. Its high strength and toughness give it significant advantages in protecting food safety, extending service life and reducing breakage rate. Therefore, in the field of food packaging, Kraft Paper Bag has been widely used and recognized.
