HIGH PERFORMANCE POLYAMIDES FOR VACUUM BAGS
PA vacuum bags are commonly used to package fresh meat cuts (pork, beef, veal) and sausages, especially for butcher shops and retail.
Their vacuum seal and barrier help extend shelflife by preventing microbial spoilage. Shrink bags offer reliable protection against moisture, gases, and off-flavors, preserving taste and aroma.
By removing air, they reduce volume, improving storage, transport, and product appearance, this makes them a key solution in food packaging efficiency.
OXYGEN BARRIER PROPERTIES - PROMYDE® BF740
PROMYDE® BF740 is a high-barrier copolyamide offering up to twice the gas barrier of standard PA6, allowing for layer downgauging and extended shelf life.
It is suitable for retort applications while maintaining barrier properties, transparency, and excellent thermoformability.
With a processing temperature of 200°C, it supports easy co-extrusion in both blown and cast processes.
Its lower OTR enables reduced PA content in PE/PA structures, improving compatibility with the PE recycling stream.
OUR PROPOSALS - vacuum bags APPLICATIONS
PROMYDE® BF36SC – EASY PROCESSING
Increased productivity and transparency, premium performance at a competitive cost, and an improved alternative to standard PA6 with enhanced properties and easy processing.
PROMYDE® BF540
Reliable PA6/66 grade for vacuum bag production.
