Foreword

This standard replaces GB/T 16719-1996 "bi-oriented polystyrene (BOPS) sheet." This standard compared with GB/T 16719-1996, the main changes are as follows:

--- The "Categories" to "Specifications", will be adjusted to a thickness ranging from 0.100mm ~ 0.700mm;

--- Increasing the terms and definitions;

--- The width deviation is adjusted to 0mm ~ + 2mm;

--- Cancellation of the product classification;

--- In a standard

5.3 in Chapter 5, "physical and mechanical properties," added the "anti-fogging" of the project;

--- In a standard Chapter 7 increased 7.1 "Batching and sampling";

--- Removed "Appendix A". This standard by the National Packaging Standardization Technical Committee and centralized. This standard was drafted. Ningbo Dongsheng Packaging Materials Co., Ltd. Wing of the Shenzhen Science and Technology Chemical Co., National Packaging Products Quality supervision Governor Inspection Center (Jinan), China Packaging Federation. The main drafters of this standard. Jiang Cai-xing, Weiming Ji, Wang Xingdong, the Kingdom of the United States, the official with the forest, Yu Guofang. This standard replaces the standards previously issued as follows:

--- GB/T 16719-1996. Biaxially oriented polystyrene (BOPS) sheet

1 Scope

GB/T 16719-2008 is the Chinese national standard on biaxially oriented polystyrene(bops)sheet, in the field of packaging and distribution of goods. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 18 July 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 January 2009. Classification: ICS 55.040, CCS A82. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the biaxially oriented polystyrene (BOPS) sheet (hereinafter referred to as sheet) product specifications, technical requirements, test methods, Inspection rules, marking, packaging, transportation and storage. This standard applies to polystyrene resin as the main raw material, made of extruded through two-way stretch with a flat sheet membrane.
