Yes, it is absolutely normal to observe some wrinkling of the adhesive when it's applied behind acrylic patches. This phenomenon occurs due to the differences in material properties between the adhesive and the acrylic. The adhesive is designed to be flexible to accommodate various applications and surfaces, while acrylic is a more rigid material.
Importantly, these wrinkles in the adhesive do not compromise the quality or durability of the patch once applied. Once the adhesive is pressed and the patch is affixed to the garment or item, the slight imperfections become negligible, having no impact on the adhesive's performance or the overall appearance of the patch.
Our products are rigorously tested to ensure they meet high standards of quality and durability, ensuring that such characteristics of the adhesive do not affect the utility or aesthetic appeal of the final application.
