On May 17, 2018, the official website of the Guangzhou Bureau of Quality and Technical Supervision announced the result of the product quality supervision and inspection of the Guangzhou plastic shopping bag in 2018. A total of 4 batches of products produced by the 3 companies were spot-checked. After inspection, 1 company produced 1 batch of product does not meet the standard requirements.
This spot check is based on the GB/T21661-2008 "Plastic Shopping Bags" standard and tests for dimensional deviation, drop test, lift test, water leakage, seal strength, dart impact, etc.
The thickness of one batch of product was spotted in this spot check and the dart drop project was unqualified. The thickness of the project failed to result in a poor endurance of the plastic bag. The reason for the failure was mainly because the company did not produce according to the standard or the production process was improper. The impact index is used to test the toughness of the plastic bag or its resistance to fracture. The failure of the project may be a problem of raw materials or production process.
