What Our Clients Are Saying

Vacuum Skin Packaging Machine

A vacuum skin packaging machine is a specialized piece of equipment that draws air from around a product and its tray, then heat-seals a flexible film directly over the item to create an airtight, form-fitting package. Shawpak Systems Ltd, based in Oakville, Ontario, supplies and installs these systems for food processing facilities, meat operations, pharmaceutical manufacturers, and industrial plants across Canada and the USA. Whether you're looking to extend shelf life, improve product presentation, or reduce material waste, understanding how this technology works and what to expect from installation and operation will help you make the right choice for your facility.

How Vacuum Skin Packaging Differs From Vacuum Seal Systems

Vacuum skin packaging and conventional vacuum sealing operate on different principles, and the distinction matters when choosing equipment for your operation. In vacuum sealing, air is removed from a pouch and the pouch is sealed; the product sits loose inside. In skin packaging, the product rests on a rigid or semi-rigid tray, air is evacuated from the entire chamber, and a thin film is drawn down and heat-sealed directly to the tray underneath and around the product itself, conforming tightly to every contour.

This conforming seal offers genuine advantages: because the film clings tightly to the product and tray with no air pockets, you get superior moisture barrier properties, longer shelf life in refrigerated or ambient conditions, and a professional retail appearance that commands higher margins. The process also uses significantly less film per package than traditional vacuum pouches, lowering material cost per unit. Shawpak Systems' technical advisory team helps facilities in Oakville and across North America evaluate whether skin packaging or conventional vacuum sealing best serves your production volumes, product types, and market requirements.

Chamber Size, Cycle Time, and Production Capacity Specifications

Industrial vacuum skin packaging equipment comes in modular sizes, and your choice directly affects throughput and floor space. Entry-level systems typically feature chamber widths between 300 and 500 millimetres, with cycle times ranging from 20 to 40 seconds per package depending on film thickness, evacuation depth, and heat-seal dwell time. Mid-range machines often accommodate trays up to 700 millimetres wide and can complete cycles in 15 to 25 seconds, making them suitable for facilities processing 40 to 100 packages per hour. Heavy-duty continuous or semi-continuous systems can exceed 200 packages per hour and handle oversized trays for bulk meat, seafood, or prepared meals.

Because cycle time and chamber dimensions directly determine your production ceiling, Shawpak Systems conducts on-site consultations at your facility to assess current throughput, future growth, and physical space constraints. The company's Centre of Excellence demonstration facility allows you to trial equipment with your actual product and packaging film before committing to purchase, ensuring the machine meets your speed and capacity targets. This consultative approach is especially valuable for facilities in Oakville, Toronto, and across the Greater Toronto Area evaluating significant capital investments.

Film Materials, Gauge, and Barrier Properties

The film used in skin packaging is not the same as standard plastic wrap; it is engineered for specific barrier performance and thermal properties. Most commercial films range from 50 to 90 microns in gauge and are typically composed of multi-layer structures: an outer layer providing puncture resistance and printability, middle layers offering oxygen and moisture barriers, and an inner heat-seal layer that bonds under controlled temperature. Materials include polyethylene terephthalate (PET), polypropylene (PP), or polyamide (PA) compositions, each with distinct oxygen transmission rates (OTR) and moisture vapor transmission rates (MVTR).

For products requiring extended shelf life-premium meat cuts, prepared seafood, specialty cheese-you may specify films with oxygen barrier ratings below 10 cubic centimetres per square meter per day. Lower barrier films cost less but suit products with shorter retail windows. The correct film choice depends on your product, storage temperature, and target shelf life. Shawpak Systems supplies films compatible with all equipment installed and provides technical guidance on film selection; this partnership approach ensures you are not left sourcing consumables from incompatible vendors after installation.

Evacuation Depth and Gas Flushing for Product-Specific Requirements

Modern vacuum skin packaging machines offer adjustable evacuation levels, typically ranging from 60 to 95 percent atmospheric pressure removal. Lighter vacuum levels preserve delicate products like fresh berries, baked goods, or soft cheeses; deeper vacuum suits denser products like meat, seafood, or processed foods where air removal maximizes shelf life and reduces oxidation. Some systems also integrate gas flushing capability, allowing you to introduce nitrogen or argon before final sealing, further displacing oxygen and extending product viability without requiring extreme vacuum.

This flexibility is critical for facilities producing multiple product lines. A meat processor in Oakville may run pork cuts at 85 percent vacuum with nitrogen flushing, then adjust to 70 percent vacuum for delicate prepared meals without equipment changeover. Shawpak Systems' on-site training program teaches your operators how to configure these parameters safely and consistently, and the company's after-sales support team remains available across Canada and the USA to optimize settings as your product portfolio evolves.

Integration With Existing Production Lines and Operator Safety Considerations

Installation of a vacuum skin packaging machine into an existing production environment requires careful planning. The equipment draws significant electrical load-most industrial models consume 3 to 7 kilowatts per cycle-and requires stable three-phase power supply and adequate cooling airflow around the chamber. Tray handling upstream and downstream must be synchronized; manual feeding introduces operator fatigue and safety risk, while semi-automatic or fully automatic tray infeed conveyors increase capital cost but eliminate repetitive strain injury and maintain consistent cycle timing.

Operator safety is paramount. The sealing chamber reaches temperatures of 80 to 120 degrees Celsius; pressure relief vents must prevent accidental hand entry during evacuation. Modern machines include interlocked safety guards that prevent chamber opening during operation, and Shawpak Systems ensures that every installation includes certified operator training covering lockout-tagout procedures, emergency stop activation, and film changeover. For facilities managing food safety and hygiene compliance across Canada and the USA, this commitment to on-site training and documented after-sales support builds confidence in your equipment investment and your team's competence to operate it safely every day.

If you are evaluating vacuum skin packaging for your food processing, meat, pharmaceutical, or manufacturing operation, Shawpak Systems Ltd is ready to discuss your specific requirements. Contact the team in Oakville to explore how this technology can improve product presentation, extend shelf life, and streamline your packaging process. They will arrange a consultation at your facility or invite you to see equipment in action at their demonstration centre.
