Interleave and Stack Foodservice Cheese

The Packaging Progressions, Inc PPI-200 is capable of interleaving and stacking cheese portions at speeds up to 300 portions per minute depending on paper length. The system cuts paper, plastic film, or metal foil of many different thicknesses directly from roll stock and also has the ability to fully wrap the portion with paper on top and bottom.

Cheese Interleaving

The pacproinc® PPI-200 line of interleavers accurately and consistently places a pre-programmed sheet of paper, film, or foil under or around your product at speeds up to 600 pieces per minute.

The paper, film, or foil sheet can be folded or wrapped around the product for ease of separation, sanitary handling, freeze release, improved shelf life, and portion control.

Interleaved (underleaved) products can be conveyed to one of our modular auto stackers for hands-free counting and auto stacking before introduction to your packaging or wrapping machine. Gain additional line flexibility with our bypass option. This option is available to accommodate processing of non-interleaved or non-stacked product and allows these products to be introduced to the packaging machine without having to take the interleaver or stacker out of the line.

All of our solutions are available as a combination interleaver and stacker or as standalone components designed to fit your application.

The PPI-200 product line is a sanitary, washdown-duty, stainless steel system. The streamlined design incorporates leading-edge Programmable Logic Controller (PLC) and servo motor technology, ensuring low maintenance and a long machine life. With compact designs available, the PPI-200 requires a minimal amount of floor space and is engineered to exceed the American Meat Industry’s 10 Principles of Sanitary Design.

The PPI-200 product line features rugged, stainless steel construction and climate-controlled (dehumidified), fully gasketed enclosures, all of which are intended to enhance the safety of your cheese products. Our PLC-based design enables easy production setup and changes, as well as networking with other equipment.

Cheese Foldover
Our equipment designs and superior construction go beyond simply addressing the need for efficient operation—ease of sanitary maintenance is central to our solutions:

  • Stand-off mounted components prevent the trapping of any product scrap improving sanitation.
  • Ground and polished welds further eliminate bacteria harborage points, making cleaning to a microbiological level possible.
  • All control cabinets and enclosures have sheet metal breaks eliminating the possibility of standing water on flat surfaces;
  • We use sealed stainless steel bearings in all food-contact areas to prevent product contamination and offer optional, antibacterial belting,
  • All machines are available with casters or leveling pads to meet your plant’s unique requirements.
  • Trays keep product scraps out of the paper path and paper tails off the floor to prevent material contamination.
  • Welded construction eliminates recessed bolt heads and other areas that could collect product cast-offs and harbor bacteria growth.

pacproinc® equipment is built to accommodate your application, with standard operating widths ranging from 3-40”. These solutions can be configured for single lane, multiple lanes, or unique groupings.

Our patented jam detectors significantly reduce costly downtime, and the PPI-200 includes Allen Bradley controls and touch screens as standard equipment. All programming is done by our in-house automation engineers, and all pacproinc® systems are supported by our 24/7 service team.

Stand-Alone Counter/Stackers

Don’t need interleaving? No problem. pacproinc® offers a variety of high-volume, multi-lane, modular counter/stackers to fit any application, and our custom design easily interfaces with upstream production equipment, end-of-line packaging machinery, or other unique production line layouts.

High-speed, sanitary, hands-free counting/auto stacking guarantees better, more accurate stacks for easier packaging and improved presentation, even for differing product requirements. And our patented in-line foldover process further extends the potential benefit.

Counting and auto stacking reduces labor and training expenses, as well as the incidence of repetitive motion injuries.

The PPI-200 increases line throughput while cutting operating costs and improving your product presentation and packaging.

CheeseLike all of our designs, pacproinc® stand-alone counters/stackers benefit from our knowledge and industry experience to include rugged, stainless steel construction and climate-controlled, fully gasketed enclosures, enhancing sanitation and food safety. Our PLC design enables easy production setup and changes to parameters like stack count, delay, speed, and portion thickness, and our solutions are easily networked with other equipment to seamlessly interface with production requirements like product changeover or stoppages.

pacproinc® can configure your PPI-200 to accept product in single or multiple lanes. We can also singulate (combine multiple lanes into a single lane) finished stacks for delivery to the packaging machine, and all stackers can be fitted with our Remote Monitoring and Diagnostic System (RMDS). Further, our complete solutions include materials and 24/7 support, along with matched rolls for multi-lane processing.

Cheese Auto-Loading


Whether you are interleaving and stacking or just stacking, many of pacproinc®’s auto stacking modules have the ability to load your counted and stacked product directly into the package. We have extensive and unique experience handling stacked food products, which allows us to introduce finished stacks directly into trays, cartons, or pockets.
