Packaging plastic strap is a common material used in securing and transporting goods. However, there is some confusion about whether or not packaging plastic strap includes glue. In this essay, we will explore the different types of packaging plastic strap, the components that make up this material, and the adhesive options available for joining the ends of the strap.
There are three main types of packaging plastic strap: polypropylene (PP) strap, polyester (PET) strap, and composite strap. PP strap is the most commonly used type of strap due to its affordability and versatility. PET strap, on the other hand, is stronger and more durable, making it ideal for heavy-duty applications. Composite strap is a combination of PP and PET, offering the benefits of both materials.
Packaging plastic strap is typically made up of a polymer material, additives such as UV stabilizers and colorants, and an adhesive or welding agent for joining the ends of the strap. The polymer material used in packaging plastic strap can vary depending on the type of strap. For example, PP strap is made from a thermoplastic polymer, while PET strap is made from a thermoplastic polyester. The additives used in packaging plastic strap serve to improve its performance and appearance. UV stabilizers help to protect the strap from damage caused by exposure to sunlight, while colorants are used to give the strap a specific color or pattern. The adhesive or welding agent used to join the ends of the strap can vary depending on the type of strap and the application. Some straps are designed to be welded together using heat, while others require an adhesive to hold the ends together.
When it comes to joining the ends of packaging plastic strap, there are several adhesive options available. Hot melt adhesive is a popular choice for PP strap as it provides a strong bond and can be applied quickly and easily. Pressure-sensitive adhesive is another option that is commonly used for PET strap. This type of adhesive is applied to the strap before it is wound onto a spool, allowing for easy application during the strapping process. Solvent-based adhesive is a third option that is used for both PP and PET strap. This type of adhesive is applied to the strap using a brush or roller and requires time to dry before the strap can be used.
In conclusion, packaging plastic strap is a versatile material that is used in a variety of applications. While there is no glue included in the strap itself, an adhesive or welding agent is used to join the ends of the strap together. The type of adhesive used can vary depending on the type of strap and the application. By understanding the different types of packaging plastic strap and the adhesive options available, businesses can choose the right strapping material for their needs.
