On November 1, 2017, GB/T 34848-2017: Thermal Shrinkage Test Method of Heatshrinkable Film was officially published by General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China and Standardization Administration of The People’s Republic of China. This standard will be enforced on May 1, 2018.
GB/T 34848-2017 was redrafted according to ISO 14616:1997: Plastics-Heatshrinkable films of polyethylene, ethylene copolymers and their mixtures-Determination of shrinkage stress and contraction stress. In comparison to ISO 14616:1997, GB/T 34848-2017 specifies more detailed testing procedures.
GB/T 34848-2017 was one of the first batches of standards planned by Standardization Administration of The People’s Republic of China. The drafting team of this standard is headed by China National Technical Committee of Standardization for Plastic Products and include Guangdong Huaye Packaging Materials Co., Ltd, Labthink Instruments Co., Ltd, Foshan Huihong Plastic Mold Co., Ltd, Southern Packaging Group Limited and Guangzhou Quality Supervision and Testing Institute.
Over the past 10 years, the drafting team did many researches and studies with shrinkable film manufacturers, users and film thermal shrinkage testing instrument suppliers. Labthink Instruments Co., Ltd undertook many sample testing tasks and gave many suggestions to the modification of this standard based on testing experience and test data. Labthink made its own contribution to the verification of the test method specified in this standard.
Labthink Instruments Co., Ltd, is always dedicated to providing customers with packaging testing solutions and helping the manufacturers fulfill the goals of quality and safety assurance through improvement of packaging testing techniques and development of high-end packaging testing instruments.
