Protection is Our Strength
The highest strength, the lowest weight. For the most demanding of packaging applications, the FibreShield family of fully extensible multiwall paper delivers an optimized shipping sack solution ideal for 2-ply pasted valve applications.
Packaging optimization starts with the paper. Our access to a high quality, northern fiber blend and a commitment to manufacturing excellence results in enhanced tensile energy absorption (TEA) in both the machine and cross directions. No matter which way you drop it, sacks constructed with FibreShield deliver the most advanced burst and puncture resistance while using up to 50% less packaging material – a win for all stakeholders throughout the supply chain.
- Purchasing and storage wins
- Reduced packaging weight – increased converting speeds
- End-use packing efficiency – clean, fast filling
- Extreme reliability – low downstream breakage rates
- FibreShield Porous®
FibreShield – ideal for use in 2-ply pasted valve perforated shipping sack applications that require maximum burst and puncture resistance including the packaging of cement, building materials, minerals and chemicals.
FibreShield Porous – builds on properties of standard FibreShield while providing an extremely open and porous sheet eliminating the need for shipping sack perforations while delivering increased strength and filling speeds ideal for today’s high speed filling lines.
An efficient alternative to flat multiwall paper, the TEA-Kraft® family of semi-extensible sack kraft paper is used in 2- and 3- ply shipping sacks to protect powdered food products, ingredients, fresh agriculture, pet food and resins. All while utilizing a lower total packaging weight and delivering increased burst and puncture resistance.
TEA-Kraft is ideal for end-users and converters alike as they look to drive increased efficiencies. The multiple options in the grade family provide an opportunity to tailor fit packaging solutions that match performance advantages with expected efficiency gains. We partner each step of the way to develop fit-for-use construction options without neglecting critical end-use requirements.
