Sack Kraft Paper - Symbol of Industrial Strength
Malbat Pack sack kraft paper is an ultra-durable packaging material designed for heavy industrial applications. This paper produced from virgin kraft cellulose is ideal for safe packaging of heavy products such as cement, flour, sugar, chemicals, mineral fillers, and construction materials. Thanks to its high tear resistance and burst strength, it safely carries loads between 25 kg and 50 kg. It can be used as outer and inner layer in multi-ply sack production.
Superior Strength and Technical Properties
In our sack kraft paper production, virgin cellulose obtained from long-fiber coniferous trees (pine, spruce) is used. This paper produced with the kraft process provides maximum fiber strength. Our grammage range varies between 70 GSM and 125 GSM. Burst strength (Mullen test) is minimum 350 kPa. Tear resistance (Elmendorf method) is over 1000 mN. Tensile strength is high in both MD (Machine Direction) and CD (Cross Direction). Our moisture-resistant treated papers maintain their performance even in humid environments. Compliance with outdoor storage conditions is provided with our UV-resistant options.
Wide Industrial Use
Sack kraft paper is widely used in cement, plaster, adhesive, and mortar sacks in the construction sector. In the food sector, it is preferred in packaging of flour, sugar, starch, milk powder, and cereal products. In the chemical industry, it is used in packaging of powder chemicals, fertilizers, carbon black, and mineral fillers. In the agricultural sector, it is frequently preferred in animal feed, seed, and fertilizer sacks. It provides high quality and durability in pet food packaging. It is ideal for industrial packaging of resin, polymer granules, and plastic raw materials. It is used as base paper in 2-6 ply sack production.
Special Applications and Treatments
Malbat Pack sack kraft paper can be offered with special treatments according to customer needs. Flexibility is increased by applying microkrep process and the filling performance of the sack is improved. Stacking of sacks is facilitated by obtaining a slippery surface with silicone coating. Waterproofing is achieved with wax impregnation. Print quality is increased with clay coating application and vibrant colors are obtained in colored prints. Stacking safety is maximized with anti-slip coating. Compliance with food safety standards is ensured with antimicrobial additive. You can create a sustainable supply chain with our FSC and PEFC certified options.
