Triune says its Bone Cover is a strong, puncture-resistant material that can reduce packaging costs by 40% over bone-guard bags and reduce leakers to 1% or less. It is available in perforated rolls, individual sheets or continuous rolls. The Ham Wrap offers a dark color that blends well with the natural rind and stays put, preventing sharp ham bones from piercing the bag. The Zublon Shrink Bags, which are printable and available in most colors, are high-clarity bags with high strength and high barrier for long product shelf life. Zublon Casings are multi-layered to provide a barrier against oxygen, fat, water vapor, aroma and ultraviolet light.
