Paper shopping bags are merchants’ favorite because they have fantastic design, favorable cost, and excellent brand promotion function. However, the bags’ bottom and handle joints are often broken during use, affecting the user experience and brand image much. Thus, as a merchant, you need to consider the paper shopping bag weight capacity when purchasing, make sure they are satisfied with your product items.
There are 3 primary factors that affect paper shopping bag weight capacity:
There are various materials for making paper shopping bags, such as coated paper, kraft paper, card paper, etc. Every type has a different toughness, appearance, and cost. Among them, toughness greatly influences the paper bag’s weight capacity. Sometimes, designers pick the paper that lacks enough toughness for a better looking. As a result, the bag may break during use because it can’t suffer from the commodities’ weight.
Even the same materials may not have the same bearing capacity because one more factor called basis weight that needs to be considered. You can understand basis weight as paper thickness simply. Generally speaking, the heavier the basis weight, the paper is thicker, or the fiber density is higher; and that also means the bearing capacity is greater. Of course, it also costs more.
In the design, the primary factors affecting the bearing capacity of the paper bag are the bottom glued and the joint cutting for handles.
Typically, almost all the paper carrier bags’ bottom is sealed by gluing. The gluing position, quantity, and quality are essential.
Some designs will pick the light basis weight paper for saving cost, and it leads to easy breaking in the practical use. For fixing this problem, the factory will provide an extra paperboard. Merchants can place it inside the paper bag bottom to get the weight-disperse feature and improve the bearing capacity.
The handle joint is another easy-breaking place of a paper shopping bag during use. The trepanning position, distance, and whether equipped with reinforcement widgets will affect the paper bag’s bearing capacity. Theoretically, the paper tape handles that are only glued on the bag’s body will be easier to break and can not bear heavy stuff.
Although it’s hard to meet the handles breaking situation during use, the style of the handles also increases or reduces the paper bag breaking probability.
Just the same as the paper, the handles are also in various materials, such as cotton, nylon, silk, and paper tape. Different style has different bearing capacity. It’s no doubt that the paper tape handles are the weakest ones.
Besides, if you choose the cotton or nylon handles, they are typically in a twisted style: single, double, or triple. The more yarns it counts, the greater weight capacity it got.
