Figure 1 Disc peeling test machine
5.7.3.1 Stick the tape on the ink printed surface of the sample, and roll it back and forth on the tape roller three times to make the required sample part completely stick, and place the sample with the tape stuck for 5min10min. 5.7.3.2 Clamp one end of the sample on disc A, and fix the exposed tape on disc B (see Figure 1). 5.7.3.3 After starting the machine, rotate the A disk at a speed of 0.6m/s~1.0m/s to peel off the tape. 5.7.3.4 Remove the sample and cover the peeled part with a 20mm wide translucent millimeter grid paper. Count the number of grids occupied by the ink layer and the number of grids occupied by the peeled ink layer respectively.
5.7.4 Test results
The ink layer bonding strength is calculated according to formula (2).
Where:
B. The bonding strength of the ink layer;
A. The number of grids of the ink layer;
A. The number of grids of the peeled ink layer.
6 Test rules
6.1 A group of products of the same variety, same specification and same production cycle with basically the same production conditions is considered a batch. (2)
6.2 Sampling test shall be carried out in accordance with the test sampling plan specified in GB/T2828.1. The sample unit for film is roll, and the sample unit for bag is piece. The minimum sample quantity for each batch is generally not less than 3 rolls for film and not less than 5 pieces for bags. 4
GB/T7707—2008
6.3 Determination of unqualified products: Each product (film or bag) shall be inspected according to the provisions of this standard. If one or more technical indicators do not meet the requirements, the product shall be unqualified. 6.4 Determination of unqualified batches: Each batch of products (film or bag) shall be inspected according to the provisions of this standard. If one or more products are unqualified, double sampling shall be conducted for re-inspection. If there are still one or more unqualified products, the batch shall be unqualified. 7 Marking, packaging, transportation, storage
7.1 Marking
The product packaging box should be accompanied by a product inspection certificate, and indicate the user unit, product name, variety and specification, quantity (film in meters, bags in pieces), quality, batch number, manufacturer name, production date, inspector code, etc. 7.2 Packaging
Film and bag products should be packed in corrugated boxes lined with plastic film (film with simple core shockproof pad core) or paper, or can be packed according to the contract requirements of the supply and demand parties.
7.3 Transportation
During transportation, loading and unloading should be done gently, collision and contact with sharp objects should be avoided, heavy pressure should be avoided, and sun protection, rain protection, and heat protection should be prevented. The packaging should be intact and the product should not be contaminated or damaged. 7.4 Storage
The product should be stored in a clean, dry, ventilated warehouse with moderate temperature. It should be kept away from heat sources and should be at least 1m away from the heat source. The product should not be piled too high to prevent heavy pressure. The product storage period is generally no more than 6 months from the date of production. GB/T7707—2008

A.2.1.1 The pressure roller is a rubber-covered metal roller with a diameter of 84mm±1mm and a width of 45mm. A.2.1.2 Rubber hardness (Shore A type) is 60~80, thickness is 6mm. Roller load 20N0.5N.
Rolling speed 0.3m/min.
A.2.2 Tensile testing machine
The tensile testing machine should be able to automatically record the peeling load and have a drawing output. A.2.3 Test method
A.2.3.1 The test room temperature is 25℃±2℃, and the relative humidity is 60%±5%. A.2.3.2 The material to be adhered by the tape should be placed under the conditions of A.2.3.1 for more than 2h. A.2.3.3 Peel off the tape, stick it to the material to be adhered, roll it back and forth on the tape roller three times, and then test it after leaving it for 5min. The tensile testing machine continuously peels at a speed of 0.3m/min, and the adhesion is calculated according to the planimeter method in 7.2 of GB/T2792-1998.
Each roll is measured three times, and the average value is the adhesive strength of the tape. A.2.3.5
