Description

Technical Field

[0001] The invention belongs to the technical field of frozen food fresh-keeping bag detection, and in particular relates to a frozen food fresh-keeping bag strength detection device. Background Art

[0002] Fresh-keeping bags are widely used in a variety of fields, including food preservation and storage. With increasing market demand, there are many manufacturers, and product quality varies greatly. Some low-quality bags may be insufficiently strong and easily break during use, resulting in loss of freshness and even contamination of stored items.

[0003] When testing fresh-keeping bags, in addition to testing their physical strength, it's also important to consider their gas barrier properties. Different bags have varying permeabilities to gases like oxygen and carbon dioxide, which can affect their preservation. Traditional bag strength testing methods are unable to detect even the smallest leaks.

[0004] To ensure high-precision testing, complex and time-consuming methods are required. High-precision gas leak detectors are typically used to test the sealability of fresh-keeping bags. These instruments place the bags in a sealed testing chamber and monitor changes in the gas pressure within the bag over a long period of time. While this method can accurately detect even tiny leaks, it's extremely inefficient for the rapid testing required in large-scale production, leading to delays in the production process.
