3 SHRINK film Low force SHRINK film Antifog SHRINK film IRRADIATE film This is a very versatile film suitable for a wide range of applications. It s shine, optics and durability. Excellent gloss, clarity, sheen. Best in class for cost and productivity. Durability as high performance overwrap film. High shrink ratio. For application that require a low force shrinkage as for example for magazine. This film offer a high transparency and protection to the magazine. Best in Sheen and gloss. Rugged puncture resistance and durability. A new antifog shrink fi lm with improved hermetic seals for reliable pack integrity. This film offers a unique anti-fog agent that prevents film fogging up under cold storage conditions. This makes it ideal choice for packaged cold foods, fruit and vegetable. Multilayer heat shrinkable film for wrapping application, this is a high performance multilayer film engineered for automatic packaging machine. It makes a clear choice for over-wrapping. Excellent sealing strength, puncture resistance, hot slip property. Model Application Width (mm) Thickness (micron) Layers Output Kg/h MHS 22 Packaging and display heat shrinkable film Up to 11 layer of polyolefin polymers Up to 250 SHS 24 Packaging and display heat shrinkable film Up to 11 layer of polyolefin polymers Up to 320 LHS 26 Packaging and display heat shrinkable film Up to 11 layer of polyolefin polymers Up to 400 The orientation line works by the so-called double-bubble process, i.e. the polymers are extruded through a circular die and immediately water-quenched to form a thick primary tube which is then re-heated up to a suitable temperature and blown to form the main bubble of thin film. The non-contact simultaneous orientation is achieve thanks to the air inflated during the start up phase. This air allows the transversal orientation while the machine direction orientation is taken simultaneously thanks to the speed different between the stretching nip roll and the tower nip roll. The bubble is cooled by air and then flattened; after the trimming of the edge, the two webs obtained rolled up in two reels. By annealing the product obtained on the biorientation equipment, it is possible to obtain heat set film such us: BOPP, BOPA, BOPET and special products. The annealing can be placed in line or off line.partial annealing can also be integrated in the orientation 4 GAP: high experience in extrusion film lines GAP: high experience in extrusion film lines 5

4 SHRINK BAG LIDDING film BARRIER SHRINK film CURING BARRIER BAG Vacuum shrink bags are the perfect packaging medium for many perishable food products, such as sub primal meat, smoked and processed meats, poultry, fish and cheese. Ideal solution for all MAP tray lidding applications of all fresh foods, irrespective of sealing technology used. High performance, very thin (28 micron) barrier shrink film. A new antifog shrink film with improved hermetic seals for reliable pack integrity. This film offers a unique antifog agent that prevents film fogging up under cold. The high sealable presentation and curing barrier bag for smoked and processed meats, cheese and fresh meats. Model Application Width (mm) Thickness (micron) Layers Output Kg/h Tritube 500 Barrier heat shrinkable film and lid Up to 11 layer with EVOH, PA Up to 50 Tritube 700 Barrier heat shrinkable film and lid Up to 11 layer with EVOH, PA Up to 90 Tritube 1500 Barrier heat shrinkable film and lid Up to 11 layer with EVOH, PA Up to 200 The orientation line works by the so-called Triple-bubble process, i.e. the polymers are extruded through a circular die and immediately water-quenched to form a thick primary tube which is then re-heated up to a suitable temperature and blown to form the main bubble of thin film. The non-contact simultaneous orientation is achieve thanks to the air inflated during the start up phase. This air allows the transversal orientation while the machine direction orientation is taken simultaneously thanks to the speed different between the stretching nip roll and the tower nip roll. The bubble is cooled by air and then flattened; The third bubble is annealed by ovens with ceramic infra-red heater The final product can be wind in tube or fat film 6 GAP: high experience in extrusion film lines GAP: high experience in extrusion film lines 7

5 MEDICAL THERMOFORMING VACUUM packaging BARRIER Medical application for blood bags, high puncture resistance, high transparency. Thermoforming film with deep draw applications up to 9 cm deep Structure: with PP/EVOH/PA ect Thickness: 100 micron microns Vacuum packaging materials, high barrier coex films/ pouches. Most of the food will need vacuum package such like meats, cheese, sea foods. Structure: Nylon/tie/PE/tie/ Nylon/tie/PE PE/tie/Nylon/tie/PE Thickness: 50 microns microns Barrier not oriented film excellent film with good transparency, which makes it the optimal solution for lamination purpose. Structure: Nylon/tie/Nylon/ EVOH/Nylon/tie/PE PP/tie/Nylon/EVOH/Nylon/tie/PE Nylon/tie/Nylon/tie/PE PP/tie/Nylon/tie/PE Thickness: 30 micron - 100microns Model Application Max. Web Width (mm) Thickness Layers Output Kg/h WQ 700 Packaging Up to 11 layer with EVOH,PA etc Up to 100 WQ 1200 Packaging Up to 11 layer with EVOH,PA etc Up to 200 WQ 1600 Packaging Up to 11 layer with EVOH,PA etc Up to 350 The molten resin is extruded in a tubular form through the die. In the path between the die and the pulling rolls, the tube is inflated until it tangencies the sizing ring which defines the width of the film that is being produced. Right after it, the film goes out of the die passing through an Air Ring, then suffering a pre-cooling and then the film passes through a sizing ring immersed in cool water. The cool water provides a thermo shock on the film because of the cold temperature, making the film to acquire brightness and high transparency that are the characteristics of the product. Afterwards the film passes through the pulling rolls, through a drier to eliminate the damp, then it passes by the device of lateral slitting (cutting) of the film and finally the roll is wound in the double winder. 8 GAP: high experience in extrusion film lines GAP: high experience in extrusion film lines 9

6 MILK and JUICE LIGHT FLEXIBLE packaging FLEXIBLE packaging NO WOVEN Multilayer laminated product for milk, juice boxes. Specifically design for long shelf life using aluminium in the laminate. Light laminated product with PET outside and PE inside ideal for product containing liquid. Multilayer product a combination of aluminium, films, metalized film laminated with extrusion. Non woven coating with PE an possible lamination with Bopp film for shopping bags, bulk bags ect. Extrusion coating and lamination is a well known technique used to produce multilayer composite laminates in one pass, thanks to the use of coextrusion technologies. This make this process very attractive. The adhesision of different substrate is done by resin. With the increasing demand for more and more square meters, extrusion coating equipment has been developed with two or even three coating stations in-line and utilising coextrusion on one or more of the coating units.
