FIELD: process engineering.
SUBSTANCE: invention relates to blow moulding. Proposed perform consists of inner and outer layers. Note here that said perform after blow moulding transforms into two-layer container. Note that outer layer of said container gets separated from container outer after feeding gas there between. Note also that one inner or outer layer comprises one additive to allow reaching appropriate temperature of blow moulding, in fact, simultaneously by both layers in heating in infrared furnace.
EFFECT: higher efficiency and reliability of blow moulding.
