GB/T 10003-2026Biaxially oriented polypropylene (BOPP) film (English PDF)

Foreword

This standard was modified in relation to ISO 17555:2003 Plastics - Film and sheeting

- Biaxially oriented polypropylene (PP) films (English version).

This standard was redrafted based on ISO 17555:2003. Appendix A lists the comparison

of the chapter and clause numbers of this standard and the chapter and clause numbers

of the international standard ISO 17555:2003.

Taking into account Chinese national conditions, this standard has made some

modifications when adopting ISO 17555:2003. Some technical differences have been

incorporated into the text, and the relevant clauses are marked with a vertical single line

in the margin. Appendix B provides a list of technical differences between this standard

and ISO 17555:2003 and their reasons for reference.

Compared with ISO 17555:2003, the main differences in this standard are as follows:

-- The product classification has been modified; the classification based on the

treated surface and non-treated surface has been deleted, and the product is

divided into ordinary type and heat-seal type according to whether it can be heat-

sealed;

-- The standard levels of major technical performances such as thickness deviation,

tensile strength, elongation at break, haze, and treated surface wetting tension

are improved;

-- Two performance indices "heat seal strength" and "glossiness" are added.

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

-- The foreword of the international standard has been deleted;

-- Informative Appendix A and Appendix B have been added for guidance.

This standard replaces GB/T 10003-1996 Biaxially oriented polypropylene plain film

and GB/T 12026-2000 Biaxially oriented polypropylene film for heat-seal.

Compared with GB/T 10003-1996 Biaxially oriented polypropylene plain film and

GB/T 12026-2000 Biaxially oriented polypropylene film for heat-seal, the main

differences in this standard are as follows:

-- The technical indices such as thickness deviation and glossiness are improved;

-- The thickness test method has been unified, changing from the stacking method

of GB/T 10003-1996 and the single-layer method of GB/T 12026-2000 to the

stacking method;

Biaxially oriented polypropylene (BOPP) film for general use

1 Scope

This standard specifies the terms and definitions, classification, requirements, test

methods, inspection rules, marking, packaging, transportation and storage of biaxially

oriented polypropylene (BOPP) films for general use.

This standard applies to ordinary (plain film) and heat-seal films for general use, which

are made from polypropylene resin as the main raw material and are produced by biaxial

stretching using the flat film method.

This standard does not apply to other biaxially oriented polypropylene films with

special functions, such as biaxially oriented polypropylene matt film, biaxially oriented

polypropylene pearlized film, biaxially oriented polypropylene film for ripping strip,

biaxially oriented polypropylene film for capacitors, and biaxially oriented

polypropylene cigarette packaging film.

3 Classification

Depending on whether there is a heat-sealing layer on the surface, it is divided into

ordinary type (Type A) and heat-seal type (Type B).

4 Requirements

120 °C±3 °C, with the stainless steel plate located in the middle of the oven. During the

test, the air is blown and the heating time is 120 seconds. Take out the specimen and

cool it to the test environment temperature. Measure the length of the longitudinal and

transverse marking lines with an accuracy of 0.5 mm.

150 mm long and (15±0.1) mm wide.

135 °C, the welding surface pressure during heat sealing is 0.18 MPa, and the heat

sealing time is 1 s. With the heat sealing part as the center line, clamp the two ends of

the specimen on the two fixtures of the test machine respectively, so that the

longitudinal axis of the specimen coincides with the center line of the upper and lower
