Waxes used in the packaging sector are generally used as part of the barrier system, to heat seal the packaging and to provide aesthetic appeal by increasing the gloss of the printed paper or card. Traditionally packaging waxes are based on paraffins, but significant improvements have been made recently in the formulations which are based on natural waxes. The significant benefit of the new developments is that hardened vegetable oils are already used extensively as significant ingredients in the foods themselves, so this removes any concerns about the possible effect of the migration of the packaging wax into the food.
 

Paraffin and Natural based Packaging Waxes

 

Kerax are at the forefront of the development and supply of both paraffin and natural based packaging waxes, over recent years Kerax has completed a program of formulating a range of 'standard' products, but we are continuously improving the performance of our waxes and always ready to use our expertise to develop waxes which are bespoke to the specific requirements of our customers.

Flexible Packaging Waxes

Paraffin and paraffin blends are used to provide gloss, freshness seals, moisture and grease barriers to food packaging.
The key benefits of using paper packaging waxes are:
Water and water vapour resistance
Gas and odour barrier (prevent loss of flavour or contamination)
Improved process efficiency through faster packaging line speeds
A 'traditional' look and feel to your product

Blending with other additives improves heat sealability, gloss, reduces friction and improves scuff resistance.

Corrugated Board Waxes

Paraffin wax is the main wax used in corrugated packaging and the main application is for food, plant and furniture packaging.  Corrugated boxes protected with waxes are three times stronger than non-wax coated corrugated boxes.
Corrugated waxes offer:
Effective moisture barrier to protect the corrugated box or the product inside.
Improved stacking and dry strength
Improved appearance
Prevents ply separation
Improved rigidity
Water and water vapour resistance
Reduced abrasiveness of Kraft board on the packaged product
