Zippack

MB8-140TW/TWW

This model from the Zippack series is characterized by its high machine performance. It processes two pouches simultaneously, achieving outstanding efficiency. It is particularly popular for small pouch formats:

• Pouch width: 70 – 140 mm
• Pouch length: 90 – 300 mm

This makes it the ideal solution for high-speed packaging of products in small quantities.

The Zippack MB8-140TW/TWW represents maximum efficiency and high performance.

It is designed for the high-speed filling of small pouches, with formats ranging from 70 to 140 mm in width and 90 to 300 mm in length.

More Details of the Zippack Operating/Guiding Priciple and Application Areas

Specific focus

Developed for the cost-effective processing of medium to large production volumes, its duplex operating mode enables almost double the output.

In its standard configuration, the machine handles pouch weights of up to 2,000 g, achieving an output of up to 80 pouches per minute.

Special Features

The operating principle differs from both classic models described previously. Unlike the other models in the Zippack Series, the Duplex MB8 – 140TW processes two pouches simultaneously.

The system automatically picks two pre-made pouches from the integrated magazine, aligns them precisely, and opens them in a two-stage process.

Two lowering chutes then descend accurately into the pouches, allowing for precise and parallel product filling. After filling, the pouches are sealed simultaneously above the zipper and automatically transferred to the conveyor belt for further processing.

Options

No:	Optional Equipment	Function \| Your Benefits
4257	Magazine extension by 1 m	For a continuous workflow with high output – without interruptions.
5994	Additional Zippack opening system (air inflation)	Inflation device for reliably opening even hard-to-open bags, including air tank with quick-release valve.
5972	Dust extraction during filling via double-walled funnel	Time-saving filling with simultaneous dust extraction of product particles. This keeps the machine body, electronics, mechanics, and packaging free from dust residues.
5978	Dust extraction directly at the bag with subsequent preparation for reliable sealing (extraction at the filling point)	The suction unit removes the dust that develops during bag filling directly at the bag opening. This keeps the machine body, electronics, mechanics, and packaging free from dust residues. The bag is then shaped to ensure reliable sealing.
5919	Device for removing residual air from the bag (air expeller)	Before closing or sealing, the air is removed from the bag. The result is compact packaging without air pockets – enabling space-saving further processing, efficient transport, and optimal placement at retail.
5912	Nitrogen flushing	Nitrogen flushing system for consistent quality, longer shelf life, and optimal product protection.
1143	Pneumatic vibrator	Used during and after bag filling for compaction, elimination of air pockets, and optimal volume utilization.
59077	Euro hole punching	The Euro hole is punched directly after sealing the bag. This ensures that the bag has been properly sealed beforehand and that your product is optimally protected.
59010	Support base for bags with higher weights	Height-adjustable device for supporting bags with heavy weights – prevents tearing of the packaging.
59004	Spoon dispenser	Automatic and hygienic spoon insertion directly into the bag.
5942m	Seam cleaning device type Tornado	Mechanical cleaning of the film in the seam area before thermal sealing – for clean, tight, and reliable seams.
5942	Seam cleaning device type Tornado	Pneumatic cleaning of the film in the seam area before thermal sealing – for clean, tight, and reliable seams.
59013	Discharge of empty bags	Automatic removal of unfilled bags.
8042	Detection of overfilled bags	Precise detection of overfilled bags using a highly sensitive photoelectric sensor.
6.40	Food-grade oils and lubricants	Use of food-grade oils and lubricants, along with instructions to minimize the risk of product contamination.
0904	Inkjet printer module for marking/coding (Videojet type 1580)	For marking/coding of bags – such as with best-before dates, batch numbers, or other important information – we use systems from well-known manufacturers such as Videojet (Type 1580), Domino, Markem, and others as per customer requirements.
5928	Bag fixer for precise marking/coding (inkjet holder with adjustable side guide)	The system aligns the bag precisely so that the coder/printer can apply markings accurately and reliably.
4404	Cover for protection against contamination (Makrolon cover)	The transparent Makrolon cover prevents dust or product residues from the feed or dosing unit from falling and interfering with the bag filling process.
1140	Buffer table / waiting station for finished packed bags (round table)	Rotary table Ø 1,200 mm, concave, made of stainless steel. The filled bags rest here safely and within easy reach until they are transferred into transport packaging. The rotation speed of the unit is continuously adjustable.
