When choosing a large yellow sealing tape with reliable quality, you can consider the following aspects.
1. Viscosity
Viscosity is an important indicator to measure the quality of sealing tape. First, the viscosity of the tape can be judged by a simple test. For example, stick the tape on a smooth surface and then tear it off quickly to observe whether the tape can stick to the surface firmly and whether there is any residue after tearing it off. If the tape can stick to the surface easily and there is no residue after tearing it off, it means that its viscosity is good. In addition, you can also check the viscosity performance of the tape under different temperature and humidity conditions. Some high-quality tapes can maintain good viscosity over a wide range of temperature and humidity.
2. Substrate quality
The substrate of the tape also has a great influence on its performance. Common substrates include BOPP (biaxially oriented polypropylene), PVC (polyvinyl chloride), etc. BOPP-based tapes have the advantages of high transparency, high strength, and aging resistance; PVC-based tapes have the characteristics of good softness and strong waterproofness. When selecting, you can choose a suitable substrate according to specific usage requirements. At the same time, pay attention to checking the thickness and uniformity of the substrate. Thicker and uniform substrates usually have better strength and durability.
3. Adhesive layer quality
The adhesive layer is the key part that determines the stickiness of the tape. A high-quality adhesive layer should have good initial adhesion and lasting adhesion. Initial adhesion refers to the stickiness of the tape when it is just pasted, and lasting adhesion refers to the ability of the tape to maintain stickiness during long-term use. The quality can be preliminarily judged by observing the thickness and uniformity of the adhesive layer. Generally speaking, tapes with thicker and more uniform adhesive layers will have better adhesion. In addition, you can also understand the type of glue used for the tape. Some environmentally friendly glues are not only sticky, but also harmless to the environment and human health.
4. Size specifications
It is also important to choose the right size specifications according to different usage requirements. Large yellow sealing tape is usually available in different widths and lengths. When selecting, consider the size and shape of the packaged items, ensure that the tape can completely cover the seal, and have enough margin for fixing. At the same time, pay attention to the thickness of the tape. Too thick tape may affect the convenience of use, and too thin tape may not be strong enough.
5. Brand and price
Brand is also one of the factors to consider when selecting sealing tape. Some well-known brands of tapes are usually more guaranteed in terms of quality and performance, but the price may be relatively high. When choosing a brand, you can refer to the reviews and recommendations of other users to understand the brand's reputation and credibility. At the same time, do not just use price as a criterion. Too low a price may mean unreliable quality. Consider the performance, quality and price of the tape comprehensively and choose products with high cost performance.
6. Appearance quality
Finally, pay attention to checking the appearance quality of the tape. High-quality tapes should have a flat surface, no bubbles, no wrinkles, and no impurities. If these defects exist on the surface of the tape, it may affect its stickiness and use effect. In addition, pay attention to whether the color of the tape is uniform and bright, and whether the printing is clear. Some special-purpose tapes may have specific printed content, such as warning signs, brand logos, etc. These printed contents should be clear and not easy to fade.
In short, choosing a reliable large yellow sealing tape requires comprehensive consideration of viscosity, substrate quality, adhesive layer quality, size specifications, brand and price, and appearance quality. Through careful comparison and selection, you can find high-quality sealing tape that suits your needs.
