Packaging material manufacturing machine that pulls material from the inside of a roll to make products like cushioning packaging. The machine has a feed mechanism with a deflection roller to introduce the material from the roll interior. This reduces the risk of web breaks compared to feeding from the outside. The feed mechanism has a guide wall that funnels the material towards the deflection roller. The guide wall covers a section of the rollers and protrudes over them. This helps deflect the material into the rollers. The feed mechanism also has a shorter guide path compared to the roller length. The shorter path reduces the material's travel distance. The machine further includes a forming device downstream to shape the material into the final product.

Manufacturing method for high-speed, cost-effective production of barrier-coated paper or cellulose-based substrates with improved gas barrier properties for use in packaging materials like cartons. The method involves coating a web of selected cellulose substrate at high speed using aqueous solutions of gas barrier polymers like PVOH/EVOH. The coated substrate is then dried while maintaining surface temps 60-95°C. Repeating the coating-drying steps once or more. This provides thin, adherent barrier coatings on the cellulose substrate without defects. The resulting barrier-coated cellulose substrate can be further coated with nanometer thin vapor deposited metal/oxide layers. The coated substrate can then be laminated into packaging materials with outer layers for protection and sealing.
