Lamination Process In Packaging Pdf

This laminating process is required when the ink and or paper used for a document is too sensitive to the heat required with thermal lamination.

Lamination process in packaging pdf. Extrusion laminating process 48mil pet unwound at 30 tension 35mil foil unwound at 10 tension 4 8mil laminated and extrusion coated sheet wound at 80 constant tension. Efficiently and safely running flexible food packaging jobs. The printed cover of books record cover jacket etc. Where the bonding agent is a wax or hot melt and is applied in a molten state onto one of the two substrates.

The adhesive lamination process can be repeated with multiple layers until the desired film structure is complete or it can be combined with extrusion lamination to create a hybrid adhesive extrusion flexible packaging lamination. Where the adhesives used do not contain. Cold lamination is a process in which only one side of a document is laminated. The bobst expertise in the design and manufacture of converting equipment includes that of extrusion coating and laminating technology.

This laminated flexible packaging product needs to be wound with a very tight start and then taper the roll s hardness as the roll builds. As an example azdel a glass reinforced thermoplastic composite made with continuous glass mat is produced using an extrusion lamination operation film continuous random orientation glass mat and molten resin are combined in a lamination process using a sandvik double belted. Lamination is the process of bonding a plastic film to a printed sheet by means of heat and pressure for protection of the work or to improve the appearance of the work. Another lamination process uses a lamination press after materials are combined in a thicker structure than film.

By combining the unique barrier sealability and structural properties of several different substrates a composite laminate is realised with the characteristics required for specialised packaging. The film used for cold lamination is much more costly than for thermal lamination but the equipment is less expensive. As a forerunner in the development of this converting process bobst today delivers leading edge and innovative technology that is extensively used in a wide variety of food and non food applications in the flexible packaging and paper and board industries. This process allows the production of paper paper or paper aluminum foil laminates that are widely used for the packaging of biscuits and bakery products.

Packaging and industrial materials laminated and composite flexible structures are being widely used for many applications. Mark andy has developed a new film lamination process which uses a combination of solventless adhesives and a zero pot life process to enable slitting of food grade flexible packaging within hours of lamination.
