Foil Structure

This foil materials is a reinforced structure with excellent barrier and mechanical properties for yoghourt packages. The foil structure is PET12/AL7/PA15/LDPE, with graphic as below.

Al7, is short for aluminum foil metal sheet with thickness 7 microns, which is the most common used thickness in flexible packaging. It is of the best barrier performance among all the film materials, which can keep the orginal flavor and fragance for a prolonged time.

PA15, which is short for biaxially orientated polyamide film, with the most used thickness 15 microns (equals to 0.6 gauge). Usually people call it nylon film. It is of excellent mechanical strength, anti-puncture resistance and high barrier performance against oxygen. When it is applied into the foil laminate, usually the final package is achieved with reinforced mechanical strength.

LDPE film, means low density polyethylene film, which is the most used inner sealing layer for the yoghourt bag. It is able to provide enough sealing strength and airtight property for the final packages.

The final thickness for this foil laminate should be 120 microns, with tolerance +-5%. and the toughness of this foil will be enough to finalize good package profile for 100 grams of yoghourt products.

The above tests are performed against each order, upon customer requirements, and you may check the exact values of this foil material in the Technical Date Sheet part of this post.

In our daily QC work, there is an more easy and reliable method to check if the bag strength is enough to meet the various conditions in the operations of filling, transport, loading and unloading, distribution. We perform drop test against each order, of course, the standard for this drop test should be decided against customer needs.
