SMF's CPP cast film extrusion line machine


Product parameter

Our CPP Cast film extrusion line machine with standard 3-layer feedblock and three extruder for the production of CPP film, But the market is respectively for demand four and five layers, five screw structure also. SMF's CPP Cast film extrusion line machine with co- extrusion flat DIE with hanger shape is able to contain fixed or variable deckling system, which allows finished product width changed Effectively. In order to achieve better performance of the separate layer feedblock, the use of multi-channel composite DIE is sometimes recommended for polymer structures with large melt viscosity or process temperature differences

Product details



CPP film with characteristics as good transparency, high gloss, good stiffness, good moisture resistance, good heat resistance, easy heat sealing and so on. CPP film through printing, bag making, suitable for garments, knitwear and flower packaging bags, Files and albums film, Food packaging, and barrier packaging and decorative metallized film. Potential applications also included food outer packaging, candy packaging (twisted conjunctiva), pharmaceutical packaging (infusion bag)

CPP film with excellent heat resistance feature. Because the softening point of PP is about 140 degrees, this kind of film can be used in hot filling, retort bag, aseptic packaging and other fields, in addition, CPP film with good characteristic as acid- resisting, alkali-resisting, Grease Resistant, which make it become the first choice of bread product packaging or laminating materials. Safe contact with food, excellent demonstration performance, flavor of the food will be affected, and can choose different grades of resin to obtain the desired characteristics


Product advantages

— Owing to their good optical and mechanical properties, cast films play a significant role in the flexible packaging market. In most cases printing, metallizing or laminating with other materials represent the subsequent processes in the value chain.

— Both, film producers and converters, expect high film quality and cost-efficient production. SUNNY can supply our customers with highly functional machines for their specific market requirements

— It is important to ensure the efficient use in every film layer in consideration of that raw material be the main part of the cost for the production of cast films. Multi-components feeding Blender system will be supply according to customer formula and requirements. Below two Feeding system for selection:

— All extruder barrels are heated using advanced heating system, thus retaining the heat in the barrel.

— FEEDBLOCK Technical Advantages
Suitable for processing multilayer and multicolor coextrusion of polymers with similar flow rate and processing temperature.
Conventional feed block structures including: insert type,mandril type,vane type. Besides, dedicated feed block for gradient film and hollow sheet.
Accurate flow channel design assures perfect processing precision.

— As a professional supplier of cast film lines, SMF relies exclusively on reliable partners for its feedblocks and flat dies.
3-layer feedblock with three extruders is standard for the production of CPP film, but there is also market demand for structures with five layers and four respectively five extruders.
In order to achieve better performance in terms of the individual layer distribution, multi-manifold laminating dies are sometimes recommended for the structures using polymers with large differences in melt viscosity or processing temperature.
