What factors affect the quality of the final product in the process of making and taping tape?

The production process of paper tape is complex and involves multiple links, and the following factors have a significant impact on the quality of the final product:

Selection and preparation of glue: Glue is the core part of the paper tape, usually using water-based acrylic pressure sensitive adhesive. The composition, viscosity, peeling strength, stickiness and safety of the glue (such as whether it contains harmful substances) will affect the performance of the tape. For example, the peel strength should be controlled at 12-16g as the best, too high or too low will affect the use experience.

Substrate treatment: As a substrate, the cleanliness and primer treatment of the paper directly affect the fit and texture of the tape. Improper surface treatment may result in poor adhesive strength.

Coating process: The uniform coating of glue is crucial, and it is necessary to accurately control the amount and speed of coating to ensure that the thickness of the glue layer is consistent. During the high-temperature drying process, the peeling strength of the glue will temporarily decrease, but this is a normal phenomenon, and the subsequent treatment needs to ensure that the ideal viscosity is restored.

Application of release paper: High quality Glasin release paper requires special treatment, such as coating with silicone oil, to ensure that the tape is easy to peel and does not remain. The control of the release force is the key, too high or too low will affect the use experience.

Production management and process control: including the quality control of raw materials, the cleanliness of the production environment, the accuracy of the equipment, etc., are directly related to the quality of the finished product of the tape. Good production management can reduce impurities and defects.

Composite and slitter: In the bonding process, the composite of paper and glue should be uniform and without bubbles, and the size should be accurate when slitter to avoid cutting to the pattern or affecting the appearance.

Formula and raw materials: Different manufacturers may have different formulas, and the quality of paper and glue raw materials used is different, which directly affects the transparency, durability and tearing of the tape.

Quality control and testing: including peel strength, stickiness, initial stickiness and other indicators of testing to ensure product compliance with standards. Continuous quality control is an important step to ensure product consistency from batch to batch.

In summary, from the preparation of the glue to the final packaging, every detail needs to be strictly controlled to ensure that the paper tape is both beautiful and practical.
