Bag Sealling Tape

Bag Sealing Tape Product Introduction
 
Bag sealing tape is a specialized pressure - sensitive adhesive tape tailored for sealing various bags, envelopes and packages. It is widely applied in logistics, food packaging, e-commerce and many other fields, thanks to its excellent adhesion and diverse functional designs that keep the contents safe during storage and transportation .

Here is a detailed breakdown:
 
1. Core Structure & Material : Its backing adopts materials like BOPP, PET, PEPA, aluminum foil and glassine paper. BOPP ensures clarity and durability, while PET boasts high tensile strength and temperature resistance. The adhesive layer mainly uses hot melt or acrylic adhesive; some food - grade tapes adopt rubber adhesive, which meets safety standards. Resealable types often have a four - layer structure including PET film and water - based acrylic adhesive, enabling repeated use.
2. Key Types & Features : It falls into two main categories. The permanent type has a tamper - evident and destructive - removal design—removing it will damage the bag, which is perfect for courier and security bags. The resealable type allows 10 - 20 times of opening and closing without residue, suitable for garment and snack bags. Besides, some products have properties like water resistance, low - temperature resistance (-18℃ anti - condensation) and ESD safety, and come in multiple colors including gold and silver, with custom printing available.
3. Common Specifications : Common widths are 9mm, 12mm, 15mm and 25mm, and lengths range from 35m to 5000m or more. For example, the 540 PET series has a thickness of 0.057 - 0.059mm, and its tensile strength can reach over 72N/10mm. It can be customized according to industrial or brand needs.
4. Wide Applications : It is used to seal courier bags, bubble mailers and medical specimen bags in logistics and healthcare. In the food industry, it seals fruits, vegetables and processed meats. It also works for electronic component packaging and luxury anti - counterfeit sealing. Additionally, it can bundle industrial parts and decorate floral arrangements.
