A large number of cosmetic and personal care products, including lotions and gels, as well as various types of liquid and powder make-up, are sealed with a peel-back lid. The performance of these seals is not only critical to the quality and safety of products, but is also a vital factor in user-friendliness. The adhesive bonds must be strong enough to withstand handling, shipping and storage without rupture or breakage, while being easy to peel back when necessary. Analysis of their efficiency will allow manufacturers to create optimum packaging, ensuring product safety and customer satisfaction.
