What is the difference between PVC tape and Bopp tape?
PVC tape and BOPP tape are both types of adhesive tapes commonly used for various applications, but they have different materials, characteristics, and uses. Here’s a breakdown of their differences: 1. Material Composition PVC Tape: Made from Polyvinyl Chloride (PVC), a type of plastic that is flexible, durable, and resistant to wear and tear. PVC tape is known for its strong, resilient nature and ability to stretch without breaking. BOPP Tape: Made from Biaxially Oriented Polypropylene (BOPP), a type of plastic film that has been stretched in both the horizontal and vertical directions, giving it enhanced strength, clarity, and flexibility. It is typically used for packaging and sealing. 2. Adhesive Type PVC Tape: Typically has a rubber-based adhesive or sometimes a solvent-based adhesive, depending on the application. It provides a strong bond on a variety of surfaces and is often used in electrical and industrial applications. BOPP Tape: Usually comes with a pressure-sensitive acrylic adhesive. This type of adhesive is strong enough for everyday use and packaging but is generally less aggressive than PVC tape adhesives. 3. Durability and Strength PVC Tape: Known for its high durability and strength, PVC tape is more resistant to abrasion, UV rays, and chemicals....

What is the difference between OPP and Bopp tape?
OPP (Oriented Polypropylene) tape and BOPP (Biaxially Oriented Polypropylene) tape are both types of packaging tapes made from polypropylene, but they differ primarily in how the polypropylene material is processed to achieve different properties. OPP Tape: This term generally refers to a type of tape where the polypropylene film has been stretched in one direction during its manufacturing process, typically lengthwise. This orientation gives OPP tape certain properties such as strength and clarity, making it suitable for various packaging needs. However, because it’s only oriented in one direction, it might not have the same level of strength or stability across both directions compared to BOPP tape. BOPP Tape: BOPP tape is made from polypropylene that has been stretched in two directions—both lengthwise and crosswise—during the manufacturing process. This biaxial orientation significantly improves the mechanical properties of the film, including its tensile strength, flexibility, and transparency. As a result, BOPP tapes are more durable, offer better adhesion, and can withstand a wider range of temperatures, making them highly suitable for heavy-duty packaging applications. In summary, while OPP and BOPP tapes share similarities in their base material, BOPP tapes generally provide superior performance due to their enhanced physical properties achieved through the...

Why is Bopp tape suitable for sealing boxes?
1. Strong adhesion The adhesive of BOPP tape (usually acrylic adhesive or hot melt adhesive) has strong adhesion and can firmly adhere to the surface of the cardboard box, ensuring that the packaged items are not easily detached or opened during transportation and handling. This adhesive force can remain effective in most environments and is particularly suitable for sealing various cardboard boxes. 2. High tensile and tear resistance The substrate of BOPP tape is biaxially oriented polypropylene film, which has high tensile strength, making the tape less likely to break, stretch or tear during use. Therefore, it can provide sufficient strength and stability when sealing the box, and can withstand the pressure of the box and the compression during transportation. 3. Durability and weather resistance BOPP tape has strong weather resistance and can maintain good adhesion in high, low, and humid environments. This means that even under changing weather conditions, BOPP tape can still ensure the sealing effect and adapt to different transportation environments. Especially for long-distance or cross-border transportation, its stability is particularly important. 4. Transparency and clarity BOPP tape has high transparency, and the packaging content after sealing is clear at a glance. Transparent BOPP tape is particularly...

Advantages of Acrylic Tape
1. Strong weather resistance Acrylic tape has excellent weather resistance and can maintain stable adhesive performance under harsh environmental conditions such as long-term exposure to ultraviolet radiation (sunlight), rain, wind and frost. Therefore, it is particularly suitable for outdoor use. 2. UV resistance ability Acrylic tape has strong resistance to ultraviolet radiation and can maintain its stickiness for a long time under sunlight without easily aging, fading, or losing its adhesion. Suitable for places that require long-term exposure to sunlight, such as outdoor advertising, building exterior walls, etc. 3. Good temperature resistance Acrylic tape has a wide temperature resistance range and can usually work in high and low temperature environments. For example, some acrylic tapes can maintain good adhesion within a temperature range of -40 ° C to+150 ° C, making them suitable for environments with extreme temperature changes. 4. Long term stable adhesion The adhesive strength of acrylic tape can become more stable and durable over time, making it suitable for applications that require long-term fixation or permanent bonding. Even after prolonged use, tape can still maintain high adhesion. 5. Chemical resistance Acrylic tape has good chemical corrosion resistance and can resist various chemicals such as oil, solvents, acid...

The difference between hot melt tape and acrylic tape
1. Adhesive components Hot melt adhesive tape: The adhesive of hot melt adhesive tape is a type of glue based on hot melt adhesive. It becomes liquid when heated and is applied to the tape substrate. After cooling, it solidifies and forms a strong bond. Hot melt adhesive is a solvent-free polymer, typically a mixture of resin and wax. Acrylic tape: The adhesive of acrylic tape is based on acrylic resin. Acrylic glue can exhibit good adhesion at room temperature and has strong UV resistance, weather resistance, and chemical resistance. 2. Curing method Hot melt tape: The curing of hot melt tape is physical curing, which solidifies the adhesive through cooling and hardening processes, so it usually requires heating to apply and bond. The tape will quickly reach its maximum viscosity after cooling. Acrylic tape: The curing of acrylic tape is chemical curing, and acrylic adhesive has strong self adhesiveness, which can quickly bond at room temperature without the need for external

Classification of tape adhesive
1. Rubber based adhesive (natural rubber adhesive) Characteristics: This adhesive is based on natural rubber and has good initial adhesion and high adhesion. It is usually used in situations that require fast bonding and high viscosity. Applicable products: commonly used for ordinary transparent tape, sealing tape, cloth tape, etc. Advantages: Strong initial adhesion and good durability. Disadvantages: Easy to be affected by temperature changes, may become brittle in low temperature environments, and has poor viscosity when exposed to moisture. 2. Acrylic based adhesive Features: Acrylic glue is based on acrylic resin and has good weather resistance and UV resistance. It usually has strong water resistance, aging resistance and adaptability to extreme temperatures. Applicable products: This adhesive is usually used for automotive tape, outdoor identification tape, high-temperature tape, etc. Advantages: UV resistance, temperature resistance, good water resistance, and strong adaptability. Disadvantage: The stickiness may not be as strong as rubber based adhesives. 3. Hot Melt Adhesive Characteristics: Hot melt adhesive is a solid adhesive that melts after heating and is applied to the surface of adhesive tape. It solidifies after cooling, forming a strong bond. Applicable products: Commonly used in packaging tape, especially in environments that require quick sealing and efficient...
