Abstract
A film wrapper for use in storing slugs and ropes of chemical anchoring adhesive includes an outer metallized polymer layer and a heat seal layer. The metallized polymer layer protects the chemical anchoring adhesive from premature reaction by providing a barrier to oxygen and light. The heat seal layer may also act as a moisture barrier layer. The chemical anchoring adhesive is divided into slugs of appropriate size for insertion into boreholes and cementing of anchor pins in the boreholes.
