The shoe tray forming machine is a professional pulp molding equipment for producing eco-friendly shoe packaging inserts. It adopts vacuum adsorption molding technology to complete continuous mass production of pulp shoe supports, shoe bottom trays and box inner liners by taking waste paper as raw materials.
The finished pulp shoe trays are widely matched with sneakers, leather shoes, casual shoes and children’s shoes. As fully biodegradable substitutes for plastic and foam fillers, they perfectly meet global plastic restriction policies and eco-packaging standards for cross-border export.
Its hourly output ranges from 1,000pcs to 7,000pcs, with total power covering 38kW–120kW. The standard industrial voltage is 380V/50Hz, and the whole machine enjoys a 12-month warranty. We can adjust machine size and functional modules according to customers’ workshop space and production targets.
Working Principle & Complete Production Flow
The shoe tray forming machine relies on negative-pressure vacuum molding technology: pulp is adsorbed onto mold surfaces via air pressure difference, then dewatered, demolded and dried to form fixed-shape pulp products. The whole production line includes 5 connected working stages:
- Despolpamento: Waste paper, corrugated cartons and waste books are put into the pulper, mixed with water to make pulp with uniform concentration, then stored in pulp tanks for continuous feeding.
- Vacuum Forming: Molds are immersed in pulp tanks. The vacuum pump generates negative pressure to evenly attach pulp to mold surfaces. The mold lifts up to drain redundant water.
- Demolding: The air compressor provides compressed air, cooperating with mechanical ejection structures to separate wet pulp shoe blanks from molds completely.
- Secagem: Wet semi-finished products are sent to drying ovens or drying tunnels. Electric heating or hot air circulation removes residual moisture to harden and shape the shoe trays.
- Trimming & Finishing: Burrs and extra edges are cut off after drying, then neat finished shoe trays are ready for packaging and storage.

Core Competitive Advantages of Shoe Tray Forming Machine

- Eco-friendly & Export Eligible. Raw materials are 100% recycled waste paper, and finished trays degrade completely without white pollution. It complies with environmental packaging access standards of EU, US and Southeast Asian markets, helping exporters avoid plastic restriction trade barriers.
- Highly Customizable for All Footwear Styles. We develop exclusive molds based on men’s shoes, women’s shoes, kids’ shoes and boots. The machine can produce single shoe supports, paired bottom trays and box inserts. Brand logos and concave-convex textures can be engraved on mold surfaces to highlight brand features.
- Lower Comprehensive Production Cost. Waste paper is low-cost raw material. Stackable pulp shoe trays greatly save warehouse and transportation expenses. Their buffer performance effectively reduces surface abrasion of shoes during transit.
- Flexible Output & Graded Automation. Production capacity ranges from 1,000 to 7,000 pieces per hour, with options from semi-automatic single-station to full-automatic multi-station lines. It fits e-commerce matching workshops, self-owned shoe factories and third-party packaging manufacturers.


- Stable Performance & User-friendly Operation. Centralized PLC touch control stores and calls production parameters with one click. The quick mold change system minimizes downtime for product switching. The machine frame adopts thick coated carbon steel or stainless steel for long service life.
- Multi-purpose with Replaceable Molds. By simply changing molds, this shoe tray forming machine can also manufacture wine pulp trays, cosmetic inner liners, electronic product buffer packaging and small household appliance holders, maximizing equipment utilization.
- Upgrade Brand Image. Custom degradable pulp trays replace cheap foam fillers, showing brands’ sustainable development concepts and increasing cooperation willingness of overseas buyers.
- Space-saving Layout. Optimized frame design reduces floor occupation compared with traditional pulp molding machines, enabling complete line layout in medium and small workshops.
