Title: THERMO-SEALING CONTROL METHOD AND PACKAGING FOR RESEALABLE PACKAGING
Abstract:
A packaging and method for controlling the seal strength between two cooperating thermo-sealable films at predetermined sealing portions, where a predetermined amount of heat is applied over a predetermined period of time. The resulting packaging is resealable after the first separation of two surfaces. The strength of the seal controlled by defining the number and dimensions of a plurality of restricted areas without a material cover that is resistant to the thermo-seal effect. The restricted area can be defined with a plurality of dots of predetermined selected shapes and dimensions. The resulting article facilitates the rupture of the packaging along a predetermined path. With this process, a fixed predetermined heat and residency time can be chosen and the seal strength can still be varied in different areas of a packaging. Non-sealable microdots with a predetermined amount of adhesive deposits also covered by a polypropylene powder deposit permit its resealing.
