How to design a packaging machine

Speicfications of the packaging machine:

How to design a packaging machine - The equipment consists of two kinds of working chamber:Thermoforming chamber&Heat sealing chamber. Vacuumizing&gas-flushing jobs are finished at the same room inside the heat-sealing chamber.Packing materials are aluminium foils or a variety of films,such as: PE/CPP/PET/PP/BOPP/BOPET/POF/PVC,transparent or opaque, printed or unprinted,flexible or rigid.They will become soft and be shaped as per the die shape under heating and air pressure(positive&negative) in the forming chamber,some cases an auxiliary mould(plug) will assist the shaping process.There are two types of films/foils:Top film&bottom film according to their usages in the packing process.Generally,film thermoforming refers to the bottom film,top film is the cover.Top&bottom films will be sealed together in the heat sealing chamber. To get a more beautiful and triaxial vision of the package, the top films also can be formed into some different shapes,it is called 'Top Film Thermoforming'.The whole process is under precisely control of PLC,continuously and automatically. Our machines are only equipped with superior compoments from quality suppliers around the world to ensure a steady & highly efficient running of the machine.

How to design a packaging machine - Packaging under vacuum extends the shelf life of products, since the biochemical degradation of the product is slowed down by the removal of the atmosphere. In the production of skin packs, trays and skin films are used that enclose the product tightly and seal the entire surface with the tray. In case of packs with modified atmosphere, the atmosphere in the pack is replaced with a gas mixture matched to the product in order to maintain the form,color and freshness of the product. This modified atmosphere packaging usually consists of carbon dioxide, nitrogen and oxygen.

illustration of working principle:

(1) Top film      (2) Bottom film
(3) How to design a packaging machine - Thermoforming chamber---The bottom film soften under heat and is shaped as per the Die(mould)'s design by combined effect of compressed air&vacuum.

(4)  How to design a packaging machine - Loading area---Shaped cavities on the bottom film can be filled with materials manually or automatically.

(5) How to design a packaging machine - Sealing chamber---Air in the shaped cavities is exhausted through a vacuum tank,meantime nitrogen or another mixed atmosphere is flushed into the cavities,then the top film is applied&sealed to the bottom film under heat as per the sealing die's design.(6) Cross cutting & longitudinal cutting units---Cutting knives separate individual packs from the sealed films.
