Abstract

Изобретение относится к полимерной композиции для уплотнительной вставки для крышек контейнера, в частности, для жиросодержащих наполнителей, которое имеет состав такой, что миграция составных компонентов в наполнитель снижена, а также к способу изготовления крышек типа "Press-on Twist-off" для контейнеров с уплотняющим элементом на основе полимерной композиции. Предложенная полимерная композиция не содержит ПВХ и включает два различных полимера, один из которых является сополимером, который включает полиэтиленовые звенья и алкилен, выбранный из пропилена, бутилена, гексена и, в частности, октена, и другой статистический сополимер, который представляет собой интерполимер линейного и разветвленного этилена и по меньшей мере одного C-Cальфа-олефина. Твердость по Шору A предложенной композиции находится в диапазоне от 45 до 90. Предложенная композиция демонстрирует остаточную деформацию при сжатии между 30 и 70% в соответствии с ASTM B395-97 способ B при 70°С.The invention relates to a polymer composition for a sealing insert for container lids, in particular, for fat-containing fillers, which has a composition such that the migration of composite components into the filler is reduced, as well as a method for manufacturing lids of the type "Press-on Twist-off" for containers sealing element based on polymer composition. The proposed polymer composition does not contain PVC and includes two different polymers, one of which is a copolymer, which includes polyethylene units and alkylene selected from propylene, butylene, hexene and, in particular, octene, and another statistical copolymer, which is a linear interpolymer and branched ethylene and at least one C 1 -C-olefin. The Shore A hardness of the proposed composition ranges from 45 to 90. The proposed composition demonstrates residual deformation under compression between 30 and 70% in accordance with ASTM B395-97 method B at 70 ° C.
