In modern logistics and production systems, industrial packaging bags not only protect products and facilitate transportation, but also are an important guarantee for ensuring safe delivery of products. As core indicators for measuring the performance of packaging bags, tensile strength and tear resistance are crucial for the evaluation of industrial packaging quality. This article will explore the importance and detection methods of these two key parameters in practical applications, and introduce information about high-quality industrial packaging suppliers.

What is the tensile strength of industrial packaging bags?

Tensile strength refers to the maximum tensile force that the packaging bag material can withstand when stretched, usually expressed in megapascals (MPa). For most industrial packaging bags used in heavy cargo, chemical raw materials or grain transportation, excellent tensile strength means stronger load-bearing capacity and higher safety.

The importance of tensile strength:

Ensure packaging integrity and prevent rupture during transportation.

Deal with complex environments such as high temperature, humidity or heavy pressure.

Increase service life and reduce replacement frequency and cost.

Detailed explanation of the tear resistance of industrial packaging bags

Another indicator that complements tensile strength is tear resistance, which measures whether the material will tear and expand rapidly after being locally damaged. This is especially critical for industrial bags that are frequently transported or need to be used multiple times.

Advantages of tear resistance:

Prevent leakage of raw materials caused by packaging damage.

Enhance the adaptability and reusability of packaging bags.

Avoid secondary losses caused by crack expansion.

How to test these two properties?

The tensile strength and tear resistance of industrial packaging bags are usually evaluated by professional testing equipment, such as electronic tensile testing machines, pendulum tear testers, etc. Qualified industrial packaging suppliers will provide product test reports to ensure that the performance of factory products meets the standards.

Common standards include:

GB/T 1040 (plastic tensile properties test standard)

ASTM D1004 (tear strength standard)

ISO 527 (plastic tensile test international standard)
