Easy to pull adhesive: difference between substrate and non substrate

Uncovering the Secret World of Easy Pull Adhesive – Analysis of the Differences between Substrate and Non Substrate Adhesive In the modern packaging industry, Easy Pull Adhesive, as an important sealing material, is widely used in the outer packaging of various products. It not only effectively seals the container to prevent leakage of contents, but also facilitates easy opening by consumers, making it highly favored. However, did you know that there is actually a distinction between “with substrate” and “without substrate” for easy to pull adhesive? Today we will explore the differences between these two types of easy to pull adhesive. Firstly, let’s understand what is easy to pull adhesive. Yila adhesive is a thin film with a special coating that causes it to detach from the substrate when subjected to certain external forces (such as tearing or stretching), thereby achieving the function of opening and closing. Usually, the easy to pull adhesive is printed and pasted onto the edge of the packaging container, forming an easy to open sealing strip. Next, let’s take a look at the specific differences between easy to pull adhesives with and without substrates. Base material easy to pull adhesive: Definition: The so-called base material easy to pull adhesive refers to a layer of strong supporting material on the back of the easy to pull adhesive. This layer of material is usually paper, aluminum foil, or plastic sheets, etc. Features: With this support layer, the substrate easy to pull adhesive can better maintain its shape stability and strength, making it suitable for environments that require high pressure. For example, the packaging of some heavy items may choose to use a base material with easy to pull adhesive to ensure the firmness of the seal. Applicable scenarios: In the fields of canned food, beverage bottle caps, and industrial product packaging, the presence of base material easy to pull adhesive can be seen. Non substrate easy to pull adhesive: Definition: As the name suggests, non substrate easy to pull adhesive is a pure gel like substance that does not add any backing material during the production process. This means that its back is in direct contact with the surface. Features: Due to the absence of additional support structures, the non substrate easy to pull adhesive is softer and more flexible, suitable for sealing various surfaces and irregularly shaped objects. In addition, due to its light weight and low cost, non substrate easy to pull adhesive is also commonly used in situations with certain environmental requirements. Applicable scenarios: In industries such as cosmetics, pharmaceuticals, and personal care products, it is common to choose non substrate easy to pull adhesive for compact and exquisite packaging design. There are advantages and disadvantages to both substrate based and non substrate based easy to pull adhesives, and the specific type chosen depends on the actual application needs. Whether it’s industrial packaging that pursues strength or consumer goods that value aesthetics, easy to pull glue can provide suitable solutions. With the continuous innovation and development of technology, we can foresee the emergence of more high-performance new types of easy to pull adhesives in the future, bringing more convenience and safety assurance to our lives.
