Hygienic Doypack Packing Machine – Food Grade Stand-up Pouch Filling for Dairy, Baby Food

Clean Room Compatible Doypack Filling & Sealing for High Sanitation Industries

Our hygienic doypack packing machine is specifically designed for industries requiring the highest levels of cleanliness. Dairy products, baby food, pharmaceutical powders, and medical devices all demand doypack packaging equipment that minimizes contamination risk. This stand-up pouch packing machine features a stainless steel sealed frame, smooth surfaces without crevices, and a sloped design that allows water and cleaning agents to drain completely. All contact parts are made of SUS304 or SUS316L food grade stainless steel.

Why Doypack for Hygienic Applications

The doypack, also known as a stand-up pouch, has become the preferred packaging format for premium hygienic products. Its gusseted bottom allows the pouch to stand upright on shelves, creating an attractive display. The doypack packing machine we offer handles these pouches with dedicated bottom spreading devices that ensure consistent opening and filling without damaging the delicate film structure.

Design Features for Hygiene

Sealed Electrical Cabinet
The electrical cabinet is rated IP65, meaning it is dust tight and protected against low pressure water jets. This allows you to wash down the entire doypack packing machine with hoses without damaging sensitive electronic components.

No Crevice or Sharp Corner Design
All sheet metal parts are welded and polished to a surface roughness of Ra 0.8 micrometers or better. Corners are radiused rather than sharp, eliminating places where bacteria can accumulate. Removable panels are sealed with food grade silicone gaskets.

Sloped Surfaces for Drainage
The doypack packing machine frame is designed with a 3 to 5 degree slope on horizontal surfaces. Water and cleaning solution run off rather than pooling. Drain holes are located at the lowest points to prevent standing liquid.

Easy Access for Cleaning
All bag contact areas including doypack bag clamps, suction cups, sealing jaws, and filling nozzles can be accessed without tools. These parts are quick-release designs that can be removed for manual cleaning or autoclaving. The sealing jaws are coated with non-stick material to prevent product build-up.

Isolation Between Product Zone and Drive Zone
The filling area is physically separated from the mechanical drive area by a stainless steel bulkhead. This prevents lubricants or wear particles from the drive system from entering the doypack product zone.

Product Applications for Doypack Packing Machine

This hygienic doypack packing machine is ideal for packaging the following sensitive products in stand-up pouches:

Baby food puree in doypacks with spout

Yogurt and dairy desserts in spouted doypacks

Pharmaceutical powders for oral suspension in stand-up pouches

Medical device components in peel-open doypacks

Protein powders and nutritional supplements in resealable doypacks

Organic fruit puree without preservatives

Pet food for sensitive digestion formulas

Cleaning Methods Supported

Our hygienic doypack packing machine supports three cleaning methods. For daily cleaning between batches, operators can perform manual wipe down using food grade sanitizer on all exposed surfaces. For deeper cleaning, the machine accepts hose wash down with water and mild detergent, with all electrical components protected by IP65 rating. For the highest standard, we offer an integrated CIP system that automatically circulates cleaning solution through the filling nozzles and doypack product contact surfaces.

Technical Highlights

The doypack packing machine operates at speeds from 20 to 60 bags per minute for hygienic models. All seals are made of FDA compliant silicone or PTFE materials. The machine can be equipped with HEPA filtered air supply to create positive pressure inside the guarding, preventing airborne contaminants from entering. An optional UV sterilization tunnel can be installed before the doypack bag opening station.
