Why Great Pack
Most packaging projects go wrong before the quotation is written, because a machine was chosen for its price rather than for the product it has to run. These three things are what we do about that.
Machine platform, dosing method and tooling are matched to your product, bag and film before a price is discussed. Special bag, film or speed requirements are reviewed by engineering first.
Frame fabrication, mechanical and electrical assembly, forming sets and controls in our own workshops, then an internal continuous run test with film before the machine is released.
Remote diagnosis, on-site commissioning, operator training and spare parts identified against your machine record for as long as you run it.
Our packaging machines
Which one fits your project is decided by the product, the bag and the speed your line has to hold — so the cards below describe capability, not a model number to order in a shop.

Not sure which machine you need? Send the six parameters and we will come back with a platform, a dosing method and the points that carry technical risk.
Send your six parametersCompany
Great Pack builds VFFS machines, stick pack machines, sachet packing machines, flow wrappers, filling systems and integrated packaging lines for food manufacturers, contract packers, machinery distributors and system integrators that need application-specific equipment rather than a one-size-fits-all machine. Core packaging equipment is produced in our own workshops; where a project needs equipment we do not build, it comes from a partner supplier — but the interfaces, the timing and the responsibility for the whole unit stay with us.
Start here
Start with the packaging task. We can work backward from your product, pack format, output and production environment.
Browse VFFS, stick pack, sachet, flow wrapping and filling platforms.
Explore machines →Start from pillow, gusset, flat bottom, stick or sachet formats.
Browse formats →Send the product, weight, bag size, film and target speed. We will recommend the system.
Discuss application →The six inputs
Everything else in the quotation follows from these six answers. If you have a sample bag, a photo or the film specification, send those too.
Powder, granule, liquid, paste or solid piece — flow behaviour, dust and bulk density decide the dosing method.
The weight or volume per bag, which sets the dosing range, the accuracy target and the size of the machine.
Pillow, gusset, flat bottom, fin seal, stick pack or sachet. The bag form decides the forming set and the sealing arrangement.
Flat width and length. The parameter most often estimated wrongly, and the machine is only as right as these numbers.
Laminated, PE, paper laminate or mono-material, which affects the sealing window, film pulling and achievable speed.
The bags per minute your production has to hold — not the maximum in a brochure. The slowest element sets the real rate.
The basic information needed for an accurate first recommendation is: product type, target fill weight, bag format, bag dimensions, film structure and target operating speed. These six inputs determine the initial machine platform, filling method and technical risk level.
Complete systems
When the application needs more than a bagger, dosing, feeding, discharge, inspection and downstream automation are coordinated so that interfaces and speeds are settled on paper instead of on your factory floor.

Secondary packaging
End of line
A single machine performs one packaging function. A complete packaging unit combines the primary packaging machine with dosing and the necessary feeding or discharge equipment. An integrated packaging line extends further into inspection, cartoning, case packing or other downstream automation, with interfaces and line speed coordinated as one project.
Package formats
Bag geometry, seal arrangement and film structure change forming, sealing, speed and changeover — which is why the package belongs near the beginning of the project, not at the end of it.
Bag format changes the forming geometry, seal arrangement, film path, changeover method and achievable speed. Pillow bags, gusset bags, flat-bottom bags, sticks and sachets therefore cannot always be treated as interchangeable formats on the same machine structure.
Application expertise
Flowability, density, dust, aeration and fill weight all affect dosing and sealing, so the filler and the bagger have to be considered as one decision rather than two purchases.
Powders are commonly filled with an auger filler, but the correct screw design, agitation, hopper arrangement and speed depend on flowability, bulk density, dust level, aeration and target fill weight. The filler and bagger should therefore be selected together.
Industries
A contract packer changing format three times a day and a coffee plant running one format all year need different answers from the same machine platform.
Applications
A case should show the conditions that decide the machine: product, format, film, dosing method, the basis of the speed figure and how the result was validated.
A representative project structure: a powder application using an auger filler and a fin-seal bag format. Final machine selection and the guaranteed speed always depend on the customer’s actual product, film, bag dimensions and test conditions.
Engineering
Forming, film handling, sealing, dosing and controls decide what the machine can hold in daily production. Core configuration is selected for the application rather than reduced to lower the purchase price.
Actual operating speed depends on bag size, bag format, product behavior, fill weight, filling-system speed, film structure, sealing dwell time and any additional operations such as coding, gas flushing or downstream handling. The slowest element in the complete system sets the real production rate.
Project execution
Decisions taken before the order stay visible through manufacturing and delivery, because every stage ends with a confirmation rather than a promise.
Product, bag, film and speed are reviewed as one set of requirements.
Machine platform, dosing method and the technical risk points.
Drawings, interfaces and the configuration that will be built.
Frame, assembly, forming sets and controls in our workshops.
Internal continuous run test, then acceptance by video or on site.
Export packing, installation, commissioning and after-sales support.
Manufacturing & FAT
Not a factory-photo gallery: the sequence below is how a machine is built, and how its performance is checked before it is released for delivery.
FAT should confirm the agreed technical parameters, package appearance, sealing quality, actual operating speed, continuous-run stability and any project-specific acceptance conditions. If a new requirement appears during FAT, it should first be checked against the original confirmed scope.
Lifecycle support
Remote diagnosis, on-site service, training and spare parts are what reduce the production risk of buying equipment from another country.
Photos, video, alarms and technical diagnosis before deciding whether a visit is needed.
Installation, commissioning and troubleshooting for projects that require field support.
Operator and maintenance guidance designed around actual machine use.
Wear parts and replacement components supported throughout machine life.
Technical resources
Selection notes written for engineers and buyers, so the first conversation starts from the same facts instead of from a price list.

Common questions
If your question is not answered here, send it together with your application details and the engineering team will answer it directly.
A vertical form fill seal (VFFS) machine forms a bag from rollstock film, fills the product vertically and seals the finished package in one automated process. It is commonly used for powders, granules, snacks, coffee, seasonings and many other packaged products.
Start with the product, fill weight, bag format, bag dimensions, film structure and target operating speed. These factors determine the required machine size, motion type, filling system and sealing configuration.
Actual speed depends on bag length and format, product behavior, fill weight, dosing speed, film, sealing dwell time and any additional operations. The complete system should be evaluated under the real application conditions rather than by theoretical maximum speed alone.
Powders are commonly dosed with an auger filler. The screw, hopper, agitation and operating settings should be selected according to flowability, bulk density, dust, aeration and target weight.
Usually yes, within the mechanical range of the selected machine. Different bag widths, forming sets and product conditions may require change parts or different forming sets, and the achievable speed can vary by format.
They can, but mono-material PE and other sustainable films often have a narrower sealing window and different stretch, friction and heat behavior than conventional laminates. High-risk applications should be tested with the actual film before final performance is confirmed.
The basic six items are product type, target fill weight, bag format, bag dimensions, film structure and target operating speed. A sample bag, photo or drawing improves accuracy.
Yes, when a project includes unusual product behavior, film, bag geometry, speed or another technical uncertainty. The purpose of the test is to verify specific risks; it does not automatically represent full-machine acceptance.
Yes. Core packaging equipment can be integrated with dosing, feeding, inspection, cartoning, case packing and other downstream systems, with Great Pack acting as the main coordination point for the packaging project.
Every machine is internally run and tested. Customer confirmation can be completed by test video or on-site FAT depending on project complexity and the agreed acceptance method.
Yes. Standard machines can often be installed with remote support, while complex projects or customers requiring field support can be handled with on-site engineering assistance.
A change affecting bag format, speed, structure, interfaces, price or delivery time should be treated as an order change. Technical, cost and schedule impact should be reviewed and confirmed before execution.
Next step
Product, fill weight, bag format, bag dimensions, film and target speed — those six are enough for a first recommendation. A sample bag or the film specification makes the answer more exact.
