5.4.12 Luminous transmittance and haze

Luminous transmittance and haze index shall be negotiated by the supplier and purchaser.

6.1 Sample status adjustment and test standard environment

It shall be performed according to the standard environment and normal deviation scope specified in GB/T 2918-1998.The temperature is (23±2)°C. The relative humidity is (50±

10) %. And the status adjustment is at least 4 hours. The test shall be carried out under this condition.

6.2 Sampling

Sampling package shall be perfect. The sampling quantity shall be enough to complete all test items. During film-reel sampling, the 3 layers of film reel surface shall be removed. Then cut and sample along the film-reel width direction.

6.4 Printing

6.5 Dimensional deviation

6.5.1 Length and width deviations of films and pouches

The length and width deviations of films and pouches shall meet the provisions in GB/T 6673-2001.

6.5.2 Thickness deviations of films and pouches

6.6 Physical-mechanical property

6.6.1 Peel force

According to the provisions in GB/T 8808-1988.

6.6.11 Heat resistance

The film is heat-sealed and made into 200mm×120mm pouches (if the product dimension is less than the aforementioned, the actual specification is used). Fill with one half to two thirds water. Then in-pouch air is exhausted and the pouch is properly sealed.

6.6.12 High temperature resistance medium

The packaging pouches are filled with 4% HAc, 1% Na2S, 5% NaCl water solution and refined vegetable oil respectively.

6.6.18 Specific chemical substances

Lead, mercury and cadmium shall meet the provisions in GB/Z 21274-2007.

Hexavalent chrome shall meet the provisions in GB/Z 21275-2007.

7.1 Group-batch

The products are inspected with a batch as the unit. The continuous-produced products with the same variety, same specification, same process and same raw material are deemed as a batch.

The longest continuous production duration shall not be greater than 7 d.

7.2 Inspection classification

7.2.1 Ex-factory inspection

Ex-factory inspection items consists of appearance, printing quality, dimensional deviation, the items listed in Table 11, and the content in Article 8.1.

7.3 Sampling

Physical-mechanical properties and other properties are randomly sampled. Enough samples are sampled from each batch for the test.

7.4 Qualification judgment

7.4.1 Judgment of unqualified items

If one of the followings. mark, appearance, printing quality and dimensional deviation is unqualified, this reel or piece is unqualified.

7.4.2 Qualified batch judgment

The mark, appearance, printing quality and dimensional deviation are judged according to Table 12.

8.1 Marks

Each product package is attached with quality certificate and indicated with product name, specification, amount, mass, batch number, production date, inspector symbol, producer's name, producer's address as well as the executive-standard number etc.

8.2 Package

Film and pouch is generally packed by paper-box, inner-lining with Kraft or thin film. It may also negotiated by the supplier and purchaser.

8.4 Storage

The products shall be stored in clean, dry and ventilated storage house with suitable temperature.

Avoid the direct sunlight. The products shall be at least 1m away from heat source and piled up properly.
