Reinforced
Shrink Film

STRONGHOLD™

Reinforced bullseyes provide increased tensile strength for carrying heavy loads. Many companies use thick film and have attempted to reinforce bullseyes by layering ink, which adds significantly to the pack’s material cost. Polypack’s patent-pending Stronghold packs consist of shrink film that is folded over on the outside ends and wrapped around the products in an overwrap style machine. The result is a double thickness of shrink film on the bullseyes, strengthening the bullseyes for carrying the pack’s weight. This allows end-users to downgauge the stock material’s film thickness while maintaining film thickness on the pack’s ends for handling. (US Patent Application No. 15450965)

Stronghold Pack Delivers Material Costs Savings of 29%

For example, a 24-pack of bottled water wrapped in a 2.5 Mil thickness film. Comparison based on 5,000’ rolls at $1.40/lb. of film:

Stronghold™ 24-Pack film size = 26” Width X 38” Repeat
1.5 Mil film roll weight = 78 lbs.
Price per bundle = $.0692

Traditional 24-pack film size = 22” Width X 38” Repeat
2.5 Mil film roll weight = 110 lbs.
Price per bundle = $.0976

Provides for a stronger bullseye for carrying purposes

  • Film around the bullseye is twice as thick, which increases strength and load capacity
  • No need for thick film or “double bump” ink to achieve a stronger bullseye
  • Run thinner gauge film than competing machines (down to 1 mil!)
    Lower film cost per pack
