When it comes to purchasing transparent elastic tape, many customers often confuse TPU elastic tape with TPU hot melt film. TPU elastic tape and TPU hot melt film, while both made from thermoplastic polyurethane (TPU), serve distinct purposes in the realm of garment manufacturing. If you are not familiar with TPU tape enough, you may easily to confuse these two different garment accessories.
Firstly, we should acknowledge that TPU tape and TPU hot melt film look similar. They are both invisible and clear transparent. And generally, they are both in shape of long tape. Then how to distinguish them?
Let’s talk about TPU tape first. TPU elastic tape are transparent, elastic straps utilized in knitting garments for shaping the shoulders, cuffs, and waist to prevent deformation during drying and washing. These tape possess elasticity but lack adhesiveness. Typically sewn onto garments, they ensure the clothing maintains its shape, providing both resilience and transparency. The primary function of TPU elastic tape is to offer structural support without compromising the garment's aesthetics.
TPU hot melt film, also crafted from thermoplastic polyurethane, differs from elastic tape in that it has adhesive properties. This film is primarily employed to bond two fabric pieces together, eliminating the need for sewing. Many seamless undergarments, including bras and panties, utilize TPU hot melt film for bonding, creating a smooth and seam-free appearance. However, garments bonded with hot melt film may face challenges such as foaming or delamination after washing.
Because of the different usages, TPU tape and TPU hot melt film generally have different packages. TPU tape usually packed in transparent plastic bag or packed in rolls. Some transparent TPU tape for bra straps will packed in wheels. No matter which package of TPU tape, you will only find one layer, TPU tape. However, TPU hot melt film generally packed in wheels, and you will find two layers: TPU adhesive tape and fixed tape.
So If your goal is to provide elasticity and shape to knitted garments, TPU elastic tape are the suitable choice. When aiming for a seamless and bonded appearance, especially in undergarments, TPU hot melt film is the preferred option.
In summary, understanding the distinctions between TPU elastic tape and TPU hot melt film is crucial for making informed decisions in garment manufacturing. Whether prioritizing garment structure with transparency or opting for a seamless, bonded appearance, choosing the right material ensures the desired functionality and aesthetics. Manufacturers and designers should carefully assess their specific needs to determine whether TPU elastic tape or TPU hot melt film align better with their garment production goals.
