The paper bag carries it all
Evaluation of the physical-mechanical performance of the paper bag for use in the transportation of retail products.
The development and implementation of paper bags has been driven by luxury, fashion and household retail, and has been used for some time in other segments such as bakeries, pharmacies, shoe stores, electronics and opticians.
To dispel possible doubts about the resistance of paper bags when carrying heavy objects, a study has been carried out to verify the capacity of paper bags to transport heavy objects.
The study was carried out by ITENE, a company that has been working on the study to verify the capacity of paper bags to transport heavy products and to carry, for example, the usual purchases made in supermarkets, department stores and bazaars.
The study was carried out by ITENE, Instituto Tecnológico del Embalaje, Transporte y Logística, with an evaluation of the physical-mechanical resistance of paper bags during transport and handling, from the time the purchase is made until it reaches its final destination.Among the main requirements to be met by shopping bags is their ability to withstand short distribution cycles characterized by factors

specific to the product contained (poorly distributed load, high density products, products with apexes and/or frozen products, etc.), as well as factors due to handling by the user (pulses, low frequency and amplitude vibrations, variable environmental conditions, etc.), all of which have a significant influence on the structural resistance of any type of bag.

The evaluation consisted of different tests
The evaluation consisted of different tests
TAKE IT ALL IN
FATIGUE TEST
To simulate the transport of the bag by a person walking at a normal pace from the supermarket to its destination.
HANDLING OR “TUG” TEST
To simulate the pulls to which the bag is exposed when the user grabs it several times by the handle.
PERFORATION TEST BY ELEMENTS WITH VORTEX OR EDGES
To simulate the transport of sharp or edged products inside the bags.

CONCLUSIONS
It is concluded that the paper bag references studied can be used by large-scale distribution for retail sales in the food sector as well as in the textile and bazaar sectors.
The results obtained in the case of the small format paper bag homologous to the plastic T-shirt type bag indicate that it can contain a load equal to or greater than 12 kg in all cases.
The maximum load to be contained in the medium-sized “all-commerce” paper bag was equal to or greater than 12 kg, depending on the type of bag tested.
The small-format bag was subjected to the same battery of tests but using a wet simulant in order to reproduce those conditions that can have a more critical effect on the paper bag, such as the humidity generated during the transport of fruits or other refrigerated foods.
Under these severe conditions, the paper bag withstood load contents equal to or greater than 8 kg.
The flat bottom bag without handle has a maximum load to be transported equal to or greater than 5 kg in the case of medium format references and 2 kg in the case of small format references, both loads are higher than those normally intended for this type of bag.
In order to check the resistance of the paper bags to the risk of perforation or tearing caused by products with edges or corners, specific tests were carried out. The paper bags tested behaved adequately without any deterioration or incidents that could affect the bag’s transport function.
