GB/T 27740-2011Cast polypropylene (CPP) film (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard uses redrafted Law Amendment uses ISO 17557:2003 "Plastics film and sheeting cast polypropylene film." this standard and ISO 17557:2003 technical differences and for the following reasons.

--- Modify the classification of the product. The surface treatment of particular products, divided by corona or flame treatment and no corona or flame treatment of the film; sealing according to product performance, divided into heat sealing and non-sealing type; according to the product's use, is divided into ordinary Films, aluminum films, films and ordinary cooking retort films.

--- Improving the thickness deviation, tensile strength values \u200b\u200bof the main technical indicators, haze, wetting tension.

--- Increasing the number of joint and segment length requirements.

--- Chapter VI increased inspection rules.

For ease of use, this standard also made the following editorial changes.

a) Remove the preface to international standards;

b) increase the informative Appendix A and Appendix B, in order to guide the use of.

This chapter lists the standard article number and the international standard ISO 17557 in information in Appendix A. Control of a 2003 reg number Lanbiao;

Given the ISO 17557 standard and the informative Appendix B. List of 2003 technical differences and their causes.
