FIELD: process engineering.
SUBSTANCE: invention relates to packing systems with sealing section for making peel sealing seam. Peel seam comprises first and second layers each having appropriate sealing surface. One or both layers have at least one or several folds or crimps. Note here that first surface can contact second surface for making sealed seam. Temperature of sealing initiation of at least of one of said layers makes 170°F (76.7°C) to 350°F (176.7°C). Modulus of elasticity of at least one of said layers in tension makes 500 MPa-2000 MPa. Note also that at least one layer of said both layers comprises thermoplastic and organic clay dispersed in at least the part of thermoplast. Organic clay comprises plate that feature mean peel magnitude of at least 20 angstroms. Seal layer features mean surface roughness of 1500-5000 angstroms.
EFFECT: reuse of food products, ease of package opening.
