Manufacturing Facility

A. Polymer Resin Is Pelletized

Polymer bags begin as resin pellets. Resin can be completely new virgin resin, or recycled resin.

Containers Of Polymer Resin Pellets Process

B. Resin Pellets Are Melted & Blown

The resin is then heated to a liquid state and blown with a stream of hot air through a ring die to create a tube of polymer film.

Resin Melting And Blowing Process In To Film

C. Film Is Extruded

The continuous tube of film is cooled and flattened through a series of rollers.

Film Extruded By Rollers Process

D. Cutting & Winding

The film tube is cut and winded in various bobbins through winding machine. These bobbins are then transferred to loom machine.

Film Folding On Rollers Process

E. Loom Machine

Here various Rolls/ bobbins are merged in loom machine where bag roll is prepared.
Then the said bag roll is cut as per the specification of customer’s order for providing the final bag.

Final Bag Making Process

Extrusion:
One of the most common plastics processing techniques covering a vast range of applications in which resins are melted, heated and pumped for processing. Extrusion machines accomplish these tasks by means of one or more internal screws. In extrusion, the material to be processed is sheared between the root of the screw and the wall of the barrel that surrounds it. This process produces frictional energy that heats and melts the substance as it is conveyed down the barrel. Melted extrudate from the machine is further processed after the extrusion phase, which typically produces pellets, sheet, cast film, blown film, fibers, coatings, pipes, profiles or molded parts. (Modern Plastics Encyclopedia 1995).

Co-extrusion:
The simultaneous extrusion of two or more different thermoplastic resins into a sandwich-like film with clearly distinguishable individual layers. This involves a process where parts are blow-molded with walls containing two or more layers of different material. Co extrusion offers wide latitude for material selection and also allows the use of recycled materials. A material with good barrier properties, for example, can be used for the inside and outside surfaces of a blow molded bottle, while recycled material can be used for the internal layer. (Modern Plastics Encyclopedia 1995).
There are many shapes and folding patterns available for poly rolls or "film" that serve as end products or precursors to making various bag configurations. Our Products are as under:
