Standard & Optional Features

Our automated packet machines include a number of desirable standard features (common to most machines). They are listed below—please ask us any questions you have. Depend on our customer service for the life of your machine.

Optional features cover a wide range of functions and packaging needs. Most Pack Zone orders are custom tailored to customer requirements—not merely off-the-shelf designs.

Standard Features

Dosing system selected and engineered for properties of your products—augers, volumetric cups, swing cups, gear pumps, piston pumps, tube pumps, counting sensors, counting templates, weigh scales, and more.
Designed for reliability, adjustment, and ease of cleaning—you benefit from years of development. Provision for convenient product and packet size changeovers is in the design. Typically more than a 10-year operating life.
304 Stainless Steel construction to resist corrosion, plus meet GMP and FDA standards. Typically, all ridgid machine parts in contact with product are SS304, plus most machine structure and cabinets. Sutiable food grade elastomers serve as seals and occasional tubular product conduits.
Servomotors are actuated by Panasonic PLCs (programmable logic controllers). Less expensive variable frequency motors often drive mixing, agitation, and suction operations. Stepping motors typically drive gripping rollers for film/packet movement.
Automated control and monitoring via Panasonic operating system, with diagnosis for many malfunctions. Adjustable speed, dosing, sealing temperature, and production count via touch screen control panels.
Adjustable packet size within a range (does not apply to width in custom mold production). Sealing temperature and pressure can also be adjusted to accommodate changes in film/​laminate/​paper. Adjustable production speed—sealing time depends on film/​laminate/​paper.
Pneumatic or electric operated sealing and cutting systems for reliability. Cutting can be straight, zig-zag, or perforations (for making strips of packets). Intermittent or continuous sealing as appropriate for machine design and film used.
Air cooling jets directed at newly form packet seals to ensure product integrity and avoid product sticking to interior packet surfaces.
Multiline machines (up to 12 parallel production lines) utilize a patented balance system for even pressure across all sealing surfaces.
Electric power specs to match your site—​50/60Hz, single/multiple phase, various voltages. Multiple phase typically required for multiline machines.
Depending on weight of machine, solid feet or various types of casters/rollers.
For multiline, shaped molds, and some pyramid machines—use external 0.6 MPa (87 psig) compressed air supply for operation.
Quiet operation at 85 db or less with cabinet doors closed. Continuous 85 db sound levels are generally acceptable for daily 8-hour exposures. Pneumatic powered multiline packing machines are the noisiest, with continous sealing single line packing machines the quietist.

Optional Features

Custom molds/cutters for desired sealing shape, 3D effect, and texture—can offer rounded seal corners for comfort.
High speed production of 100-160 packets per minute per line. Achieved by upgrading dosing systems and using servo-motors for all drives—without chains (no-chains also reduce maintenance).
316 Stainless Steel construction to resist more corrosive products, plus meet GMP and FDA standards. Additional custom materials/plating for corrosion resistance are also available.
Ultrasonic sealing for additional heat reduction in the sealing process—required by some films such as nylon mesh.
Interlocks for auto-shutdown when safety doors are open (as required by some OSHA and other regulations).
Second horizontal cutter for chain (strip) production of packets to make both clean and perforated cuts, resulting in repeated strips (e.g. strips of three packets for orderly packing).
Notch cutter for opening point. Hole punch for packet to hang on display hook.
Network and Wi-Fi monitoring/​control—including via mobile phone app.
Conveyor, auger, and vacuum systems to keep hoppers full of product. May include level switches.
Carton forming, packing, and sealing line. Various easy-open tabs are available.
Printers for packet dates/​lots/​graphics—ink-roller/​ribbon/​thermo-transfer/​laser. Laser functions by etching a layer from packet film—exposing a contrasting color below the top layer. Ask about color options for printers.
Mixer in feeding hopper to keep slurries and other mixes uniform. Vibrators as to promote flow of troublesome products.
Double walled feeding hopper with electric heating for keeping viscous product at a set temperature.
Multiple dosing units can be used to combine different products into the same packet. Dosing units may be a combination of different types.
Controlled air or nitrogen flush system to keep product dry and/or fresh. Dust and vapor control systems for problematic products.

Feature Photos

Below find photos and comments on a number of standard and optional features of packet machines from the Pack Zone. If there are other photos you would like to see, please let us know.

hopper mixer

Hopper Mixer

Some products can separate/settle/stratify with time and machine vibrations. An optional hopper mixer with a variable speed drive can address that issue.

ink roller type printer

Ink Roller Printer

An ink roller printer is typically used to imprint date/​lot/​expiry on stick and pillow packets. Seen here with a control unit.

ribbon printer on a multiline packing machine

Multiline Ribbon Printing

A single ribbon prints all packets on a multiline machine—for a while. Ribbon printers are also typically used to imprint date/​lot/​expiry on three and four seal sachets.

cooling jets on a multiline machine

Multiline Cooling Jets

Two sets of four thin-tube air cooling jets are seen above on this four-line packet machine.

continuous horizontal heat sealing

Continuous Sealing

Continuous heat sealing is quieter than the "clapping" type, but requires better QC on film. Horizontal seal rollers include thin horizontal springs to push air out of the packets. Vertical seal rollers are seen on the right, which also pull the film down as packets are formed.

ultrasonic sealing

Ultrasonic Sealing

A sealing apparatus is seen protruding though the large hole in the left side cabinet. Ultrasonic sealing generates localized heat from vibration, resulting in faster cool-down. Blue gripper wheels move film downward via stepper motors—an example being seen in the next photo.

stepper motor inside machine cabinet

Stepper Motor

Seen inside a machine cabinet, connected to a toothed drive belt, is a stepper motor for moving film in discrete steps as packets are formed.

machine with several hoppers to combine products

Combining Products

Several products can be combined into a single packet by using multiple instances of dosing units. Here we have four hoppers feeding volume cups and three feeding vibration counters.

The bit of magic occurring within this cabinet benefits from two cooling fans. Also note the locking mechanism on the casters.
