Pupa 1000
Automatic bag making machine for the production of shoppers and large shopping bags from plastic films.
Pupa 1000 is a new welding machine for the production of bottom-seal open-mouth bags, shoppers and large shopping bags from tubular films.
PE tubular film materials include: HDPE or LDPE.
Versatility, reliability, welding quality and simplicity of use are the main features of this bag machine machine.
Pupa is equipped with special SHOPPER SEALING BARS in the central area of the welding machine, for the production of double seal bag stacks.
The bag stacks are placed on the collection belt, ready to be punched to obtain shoppers or large shopping bags. (The cutting die can be supplied separately).
This machine is especially suitable for printed materials; side gusseting can be performed on request, as part of the processing cycle.
By excluding the shopper sealing function, the machine can be used for the production of “open mouth” sacks and bags confirming its versatility characteristic.
Changes in length and thickness do not lead to production downtime.
All functions of the welding machine are programmed via a terminal with a large display for entering production parameters and displaying diagnostic messages.
The Pupa 1000 welding machine is completely protected by a transparent makralon cover that guarantees total safety of the operators while allowing continuous control of production.
The machine conforms to standards
