Feature focus: On Meypack Stretch film wrapping

 

Meypack Stretch film wrapper

As a supplement to the shrink wrapper and shrink tunnel, our stretch-film wrapper from the FW Series continuously wraps products in a stretchable film.

The film rolls, which are positioned opposite each other, can achieve an output of up to 60 film packs per minute.

This type of packaging is particularly suited for frozen products. Low electricity and film consumption are just two of the many advantages provided by this machine.

SN Innovative solutions: Product example – Screen wash

 

SN Innovative solutions: Product example – Screen wash

The task: A Scandinavian producer seeks to fill three liters of screen wash. The packaging shall be user-friendly (light weight, easy handling, little waste) and inexpensive to produce. In addition, the easily inflammable content must be packed securely and well presentable in store.

The solution: A pre-made pouch with corner spout and carrying handle is flled and sealed on our horizontal rotary pouch fller FS 830 with servo-driven pump. The laminate has to withstand both the heavy weight and the ethanol-containing product.

For this project the FS 830 was equipped with a few new technical developments. The main focuses were:

  • safe production
  • high production rate
  • little foam generation

In order to meet these requirements SN developed the following solutions:

  • special pouch opening
  • double-filling
  • ideal size of the filling heads
  • removing foam remains by suction air

After entering the horizontal rotary pouch filler the pouch is pulled and held open completely by means of suction cups on the upper and lower part of the pouch and two inserting, synchronized swivels.

In order to meet the requirements of this special product and output rate the filling process is divided between two machine stations. A servo-driven filling head is inserted rapidly into the pouch, lifted up slowly during the filling process (1,5 liters) and finally, when the pouch is filled to its half, removed again quickly. This process is repeated at the next station where the pouch receives the second 1,5  liters in the same way.

The advantage of this technical development: the foam building of the product is reduced to a minimum.

Finally, the little remaining foam and air are sucked off (optimizing the pouch volume). The fawless seal is created by a thermic double-seal during which the filled pouch is supported mechanically. At the final of the eight stations of this rotary table the head-seal is cooled and the pouch transferred to the outlet conveyor belt.

In order to meet the requirements of a product containing ethanol, the machine was built in accordance to ATEX guidelines and is TÜV certified. Prerequisites for this certifcation were, for example, the stainless steel execution (wet cleaning) with circumferential gutter as well as an ethanol-exhaust and gas detectors which are placed above and below the machine table.

The FS 830 is suitable for pouch sizes up to 300 x 420 mm. Thanks to tool-free format change-overs, product change times below 15 minutes can be realized. The setting of the formats is furthermore simplifed by mounted scales. Via integrated recipe control all format-depending parameters can be saved and recalled through the SN Smart-Touch operator panel.

SN Innovative solutions: Snacks in stand-up pouches with zipper

 

SN Innovative solutions: Snacks in stand-up pouches with zipper

The task: A market leader for nuts and dried fruits would like to bring out selected specialties to the best point-of-sale. The products are considered healthy snacks for in-between meals and should be sold in appealing stand-up pouches with resealable press-to-close zipper. Great fexibility regarding pouch sizes, product variety and quantity must be guaranteed as well as the inclusion of hygiene and special occupational safety and health regulations.

The SN solution: The horizontal working FM 060 series form, fill and seal pouch machine is tailor designed and constructed for the customer. From the SN auto-splicer, via the thermal transfer printer used in the continuous part of the machine, the digital displays for side seal position and pressure, right through to the easy swivel top seal mechanism: all components are precisely aligned to the needs of the customers. These are quick and easy pouch size change and – as on all SN packaging machines – a very good cleaning possibility are incorporated.

Details: The SN developed auto-splicer reduces the film change to a minimum and material usage. The new film roll is prepared on the cutting and gluing table of the splicer and automatically inserted into the machine as soon as the material of the current reel runs out. The pouch with the splice is detected on the Rotary turret and rejected. The machine continues to work when changing film thanks to the built-in film buffer at full speed, resulting in maximum effciency of the line. The space saving thermal transfer printer positioned at the folding plow transfers the required information (e.g. the expiry date of the product) in the gusset of the pouch. The zipper is inserted into the pouch and film further advanced to the seal stations.

The fine adjustment of the seal position can be done on the fly and can be visualized by means of a digital display. The sealing jaw pressure gauges are also equipped with digital displays and ensure the accurate reproduction of the seal pressure on the film at machine speed. The high performance heat sealing jaws, made of a special alloy, ensure the perfect temperature distribution across the entire seal surface via sophisticated electronics, even at maximum production speed. The side seal is immediately cooled after sealing and the euro hang hole, as well as the tear notches are punched out. The film is then cut into individual pouches and transferred into the 8 station rotary turret.

Special features of the rotary turret:

  • Sensor for the correct position of the pouches in the gripper
  • Electronically controlled flow meter for the nitrogen gas flushing (parameters can be saved in recipe management and easily recalled)
  • Top seal monitoring for the detection of foreign objects in the top seal and rejection of the identifed pouch
  • Exhaust unit on the top seal cleans the sealing jaws between each sealing
  • Easy-swivel top seal unit for easy cleaning of the sealing jaws
  • Automatic rejection of faulty pouches
