FIELD: process engineering.
SUBSTANCE: invention relates to sandwiched films for packing of consumer products, particularly, to resilient package made from recoverable stock. Resilient packages consist of material containing, in fact, no oil-based untreated compounds. These packages contain sealant with bio-base taken in amount of about 85%. Said sealant is laminated on outer substrate containing said bio-base in amount of about 95% in binder ply which can comprises extra extruded substrate. Extruded substrate contains bio-base in amount of at least 85%. Inks can, not necessarily, be applied on either side of outer substrate while outer substrate outer surface can additionally include a lacquer. Protective material ply can be applied or laminated between first binder ply and outer substrate.
EFFECT: resilient package made from recoverable stock containing, in fact, no oil-based untreated compounds.
