Plastic Pallet Styles
Different materials and constructions serve different purposes. We carry five major types of plastic pallets to cover any application — from lightweight nestable export pallets to heavy-duty steel-reinforced rackable units.
HDPE Pallets
High-Density PolyethyleneThe most common plastic pallet material. HDPE offers excellent chemical resistance, is easy to clean, and can withstand temperature extremes from -40 F to 160 F. Ideal for food and pharmaceutical applications. HDPE has the best balance of strength, chemical resistance, and cost — making it the default choice for most plastic pallet applications.
- Chemical & moisture resistant
- FDA/USDA compliant
- Extreme temperature tolerance (-40 to 160 F)
- Longest service life
- Impact resistant at low temps
- Easy to sanitize and pressure wash
Polypropylene Pallets
PP ConstructionLighter than HDPE with good rigidity. Polypropylene pallets offer an excellent strength-to-weight ratio, making them ideal for air freight and applications where pallet weight is a key consideration. PP has a higher melting point than HDPE (330 F vs 260 F), making it better for hot-fill food processing and autoclave sterilization.
- Lightweight construction (15-30% lighter)
- Higher melting point than HDPE
- Good impact resistance
- Lower cost than HDPE
- Ideal for air freight
- Autoclave compatible
Nestable Pallets
Space-Saving DesignEngineered to nest inside each other when empty, reducing storage and return shipping costs by up to 70%. The nine-leg design allows pallets to stack vertically with minimal footprint. Nestable pallets are the standard choice for export shipping because they take up less container space on the return trip and are ISPM-15 exempt.
- Reduces storage space 3:1 ratio
- Lower return freight costs (70% less)
- Nine-leg standard design
- Lightweight for shipping (15-22 lbs)
- ISPM-15 exempt
- Ideal for one-way and export
Stackable Pallets
High-Load DesignBuilt with a solid or perforated deck and reinforced structure designed for heavy stacking. These pallets can support significant top-load weight, making them ideal for high-rack warehousing. Stackable pallets typically have a three-runner or perimeter base design that distributes weight across a larger surface area.
- High static load rating (up to 30,000 lbs)
- Reinforced deck structure
- Flat top for even loading
- Ideal for stacking goods 5-6 high
- Perimeter or three-runner base
- Compatible with conveyor systems
Rackable Pallets
Warehouse ReadyThe strongest category of plastic pallet. Engineered with internal reinforcement (often steel rods) to handle rack-spanning loads without sagging. Built for automated warehouse and distribution center racking systems where the pallet must span between two beams with full load. These are the premium plastic pallet option.
- Steel-reinforced options available
- 2,500+ lb racking capacity
- Automated system compatible
- Longest service life (200+ trips)
- Precise, consistent dimensions
- Available with RFID integration

Cleaning & Sanitization Guide
One of the biggest advantages of plastic pallets is their ability to be thoroughly cleaned and sanitized. Unlike wood, plastic's non-porous surface does not absorb bacteria, chemicals, or odors. Here's how to maintain hygienic plastic pallets for your operation.
Pressure Washing
The most common cleaning method. Hot water at high pressure removes dirt, debris, and most contaminants. Suitable for general warehouse use and non-food applications.
Best for: General use, warehousing, manufacturing
Chemical Sanitization
Quaternary ammonium, chlorine-based, or peracetic acid solutions kill bacteria and pathogens. Required for food-contact and pharmaceutical applications. Must be followed by a clean water rinse.
Best for: Food & beverage, pharmaceutical, cleanroom
Steam Cleaning
Superheated steam kills 99.99% of bacteria and viruses without chemicals. Ideal for organic food processing and facilities that avoid chemical sanitizers. Fast drying time.
Best for: Organic food, chemical-free facilities
Automated Wash Systems
Conveyor-fed wash systems that clean, sanitize, and dry pallets at production speed. For operations processing 100+ pallets per hour. Combines pressure wash, chemical sanitization, and forced-air drying.
Best for: High-volume operations, food processing plants
Chemicals Compatible with Plastic Pallets
Most common food-service sanitizer. Safe for HDPE and PP at recommended dilutions.
Effective sanitizer at 200 ppm. Rinse thoroughly. May discolor light-colored pallets over time.
FDA-approved no-rinse sanitizer. Excellent for food contact surfaces. Safe for all plastic types.
Common for pharmaceutical and cleanroom applications. Fast evaporation, no residue.
Can cause surface cracking or stress whitening on some plastics. Avoid prolonged contact.
HDPE resists most acids, but concentrated sulfuric or nitric acid may cause degradation over time.
Pro Tip: Sanitization Schedule
For food and pharmaceutical operations, we recommend sanitizing plastic pallets every time they return to your facility. For general warehouse use, a monthly deep clean is sufficient. Keep sanitization logs for auditing — we can provide templates.
Temperature Range Specifications
Plastic pallets perform across a wide temperature range, but different materials behave differently at temperature extremes. Understanding these limits is critical for cold storage, freezer, and hot-fill applications.
| Environment | Temp Range | HDPE Performance | PP Performance | Recommendation |
|---|---|---|---|---|
| Deep Freeze | -40 F to -10 F | Excellent — maintains flexibility and impact resistance | Caution — becomes brittle, risk of cracking | HDPE strongly preferred |
| Standard Freezer | -10 F to 20 F | Excellent — no performance loss | Good — reduced impact resistance | HDPE preferred |
| Refrigerated | 32 F to 45 F | Excellent | Excellent | Either material works |
| Ambient Warehouse | 45 F to 100 F | Excellent | Excellent | Either material works |
| Hot Warehouse | 100 F to 140 F | Good — slight softening possible | Excellent — higher melting point | PP slightly better |
| Hot-Fill Processing | 140 F to 200 F | Caution — approaching softening point | Good — well within range | PP strongly preferred |
| Autoclave | 250 F to 275 F | Not suitable — above melting point | Marginal — at upper limit | Stainless steel or special PP |
Total Cost of Ownership
Plastic pallets cost more upfront than wood, but their 10x longer lifespan makes them cheaper per trip in many applications. Here is a side-by-side comparison of total cost of ownership over a 5-year period for a fleet of 1,000 pallets.
Wood Pallets (Used)
Replace every 15-30 trips
Plastic Pallets (Used)
Replace every 100-200 trips
Plastic Pallets (New)
Replace every 150-250 trips
The Bottom Line
Used plastic pallets from Stockton Pallet Co. deliver the lowest cost per trip of any option — $0.19/trip vs. $0.34/trip for used wood and $0.41/trip for new plastic. Over a 5-year period with a fleet of 1,000 pallets cycling 50 times/year, used plastic saves $36,250 vs. used wood and $53,250 vs. new plastic.
Why Choose Plastic?
Hygienic & Sanitary
Non-porous surface does not absorb liquids, bacteria, or odors. Easy to wash, sanitize, and sterilize. FDA and USDA compliant for food and pharmaceutical use. Passes FSMA audits with ease.
Extreme Longevity
Plastic pallets last 10x longer than wood on average — 100-250 trips vs. 15-30. They do not splinter, crack, rot, or absorb moisture. One plastic pallet replaces dozens of wood pallets over its lifetime.
Consistent Weight
Unlike wood, plastic pallets maintain the same weight throughout their life — no moisture absorption. Predictable tare weight simplifies shipping calculations and avoids overweight surprises.
No Nails or Splinters
Eliminates workplace injuries from protruding nails, staples, and splinters. A safer choice for workers handling pallets daily. Reduces workers comp claims and OSHA incident reports.
ISPM-15 Exempt
Plastic pallets are exempt from ISPM-15 heat treatment requirements because they cannot harbor insects or plant pests. Ship internationally without fumigation, treatment stamps, or compliance paperwork.
Color-Coded Tracking
Available in multiple colors for easy visual identification in busy warehouses. Blue, black, red, green — use color to code product lines, zones, or customers. RFID integration available on rackable models.
