FIELD: process engineering.
SUBSTANCE: invention can be used for fabrication of packages and containers. Polymer particles comprise PTFE, copolymers and over 75% of fresh polyester. Particles feature characteristic viscosity making at least 0.72 dl/g, 10 hpm of residual acetaldehyde, or less, and at least two melting peaks. One of said melting peaks represents low temperature melting peak varying from 140°C to 220°C. Endothermic area of polymer melting has absolute value of at least 1 J/g. Crystallinity of particles makes up to 20% of maximum possible magnitude. Performs and bottles made from said particles are produced by melting them in moulding machine cylinder.
EFFECT: reduced power consumption, higher quality of end products.
