Food-grade plastic trays are specifically designed and manufactured to meet strict safety standards for direct contact with food. Their primary goal is ensuring food safety through non-toxic materials, safe manufacturing processes, and reliable performance. Crucially, these trays must not contaminate food. Compliance with recognized regulations like FDA (USA), EU 10/2011 (Europe), or GB standards (China) is essential.
01
Core Difference: Safety Certification
The biggest difference is official approval. Non-food-grade trays haven't passed the required food safety tests or government regulations. They lack proof they're safe to touch what you eat.
02
Materials Used
These trays often cut corners. They might use recycled plastic (source unknown), industrial-grade plastics (not meant for food), or contain questionable additives like certain plasticizers or flame retardants banned for food contact.
03
The Real Risk
Here's the scary part: using them for food means chemicals could leak into your food over time. You might not see or taste it, but it could pose a genuine health hazard. It's simply not worth the risk.
What are the key features and elements of food grade plastic pallets?
Meeting Food Safety Rules & Standards
Food-grade trays must use officially certified safe materials. Different regions have different rules:
USA: Must meet FDA (Food and Drug Administration) requirements.
Europe: Complies with EU food safety regulations.
China: Meets GB 4806 national food safety standards.
Other countries (e.g., Japan) have their own standards.
They also undergo migration testing – simulating real-use conditions (like temperature, contact time, food type – oily/watery/alcoholic). This checks if chemicals (plastic particles, colorants, stabilizers) transfer into food. Any migration must be well below safety limits – no health risks, no odd tastes/smells.
Using Safe Raw Materials
The plastics themselves must be "clean":
Virgin plastic preferred: Made from pure, food-grade new plastic pellets. Recycled plastic is usually avoided (unless certified food-safe) due to unknown contaminants.
Safe additives only: Colorants, stabilizers, antioxidants, or softeners added must be food-grade and non-toxic.
Common plastics used:
HDPE (sturdy plastic): Most common. Tough, freeze-resistant, chemically stable, easy to clean.
PP (heat-resistant plastic): Handles boiling water, flexible, widely used.
PE (softer plastic): Lightweight/bendable, good for flexible trays.
Specialty plastics: Used for extreme cold/heat/harsh conditions.
Strict Production Controls
Clean manufacturing matters:
Spotless factories: Dust, grease, or debris contamination must be prevented.
Dedicated equipment: Ideally made on production lines only for food-grade items
Performance Features
These trays must be practical, durable, and safe:
Easy to clean/sanitize: Smooth, seamless surfaces for thorough washing/steaming/disinfecting.
Tough & durable: Withstands stacking, impacts, and transport wear-and-tear.
Resists food chemicals: Handles oils, acids, salt, sugar, and cleaning agents without degrading.
Temperature-tolerant: Stable performance whether frozen, refrigerated, room-temp, or heat-sterilized (no warping/chemical leaks).
No plastic smell: Zero odor transfer to food.
What are the main application scenarios?
Food Processing Plants
Handling raw materials, semi-finished goods, and finished products during transfer, movement, and temporary storage throughout production stages.
Central Kitchens & Catering
Used for sorting ingredients, food preparation, storage, and distribution within large-scale food service operations.
Fresh Produce Retail & Cold Chain Logistics
Transporting and storing meat, seafood, fruits, vegetables, and dairy under refrigerated or frozen conditions.
Bakery Operations
Supporting bread and pastries through stages like proofing, cooling, storage, and final delivery to stores.
Beverage Industry
Essential for the warehousing and transportation of bottled water, soft drinks, and other beverages.
Pharmaceutical Sector (Specific Uses)
Moving materials requiring high hygiene standards, often under stricter GMP regulations than food handling.
Characteristics of food grade pallets
Common Sizes of Food-Grade Pallets
Food-grade pallets are typically sized according to industry standards and usage needs. Common dimensions (in mm) include:
Standard sizes: 1200×1000 (European standard), 1100×1100 (Asian standard), 1200×800 (suitable for racks)
Medium pallets: 1000×800, 800×600 (ideal for small-scale handling)
Custom sizes: Adjustable per requirements, such as 600×400 (for bakery trays) or 1400×1200 (large-scale storage)
Load Capacity Requirements for Food-Grade Pallets
There is no universal standard for load capacity, but pallets must meet practical demands based on material and design. Common ranges include:
Static load (stacking): 500kg–2000kg (e.g., heavy-duty HDPE pallets).
Dynamic load (handling): 300kg–1000kg (must account for forklift impact).
Rack load (storage shelves): 200kg–800kg (requires reinforced structure).
