Standard atmosphere for handling and testing of pulp, paper and paperboard samples 3.1 Aluminum foil lining paper is divided into two types: B and C. Aluminum foil lining for wall paper and moisture-proof packaging. 3.1 According to the processing equipment, the base paper is divided into two types: Type 1 - single-sided smooth aluminum foil lining paper, mainly suitable for processing machines with a speed greater than or equal to 100m/min; Type - double-sided smooth aluminum foil lining paper, mainly suitable for processing machines with a speed greater than or equal to 100m/min. 4 Technical requirements and test methods
4.1 The technical indicators of aluminum foil lining paper must comply with the provisions of Table 1. Approved by the Ministry of Light Industry of the People's Republic of China on April 15, 1993, implemented on December 1, 1993

4.2 Aluminum foil backing paper is in rolls, roll width 365mm, 380mm, 410mm, 476mm, 490mm, other colors, sizes and quantitative papers can be produced according to contract requirements.
The allowable deviation of paper width shall not exceed ±3mm, and the deviation of paper roll diameter shall be ±50mm. 4.3 The fiber structure of the paper should be even and there should be no serious clouding. The paper surface should be flat and there should be no folds, wrinkles, incompleteness, holes, streaks, spots, cracks, sand and hard blocks that affect the appearance of the paper. 4.4
The color tone of the same batch of paper should be consistent and there should be no obvious difference. 4.5
4.6 The cutting edge of the paper roll should be neat and clean, the end surface should be flat, there should be no cracks or missing edges, the bow should not exceed 10mm, and the serration should not exceed 3mm.
There should be no more than 6 joints per roll of paper, and the joints should be glued with tape or impermeable glue. The joints should be good, and the glue should not affect the upper and lower layers and 4.7
Both ends, and the ends of the rolls should be marked with colored paper strips or colors. 4.8 There should be no impurities such as scraps of paper and dust in the paper roll. 4.9 The moisture content of the paper should be consistent, and the edges of the rolls should not be loose or tight. 5 Inspection rules
5.1 The quantity delivered at one time is a batch, but not more than 30t. Each roll of paper shall be accompanied by a product quality certificate. 5.2 The purchaser has the right to inspect the quality of the product according to this standard. If there is any objection to the quality of the product, the supplier shall be notified within half a year after the arrival of the goods, and samples shall be taken together for re-inspection. If the re-inspection does not meet the requirements of this standard, it shall be judged as a batch failure and the supplier shall be responsible for handling it. 5.3 Delivery inspection shall be carried out in accordance with GB/T2828. The sample unit is roll. 5.4 The sampling and handling of samples before inspection shall be carried out in accordance with GB/T450 and GB/T10739. 314

6.1 Packaging and marking shall be carried out in accordance with the provisions of GB/T10342. 6.2 The roll should be made of a layer of plastic film and a layer of kraft paper with a basis weight of 60-80g/m2. The end surface should be pleated and sealed with a wooden plug. 6.3 The paper should be properly stored to prevent the influence of rain, snow and ground moisture. 6.4 During transportation, a canopy and clean transportation vehicle should be used. Paper pieces are not allowed to be dropped from a height. Additional remarks:
This standard was proposed by the Paper Industry Department of the Ministry of Light Industry. This standard is under the jurisdiction of the National Paper Standardization Center. This standard was drafted by Shanghai Daming Paper Factory. The main drafters of this standard are Chen Rufang and Sheng Xuemin. From the date of implementation of this standard, the former Ministry of Light Industry standard QB205-1973 "Aluminum Foil Lining Paper" will be invalid. 315
