Plastic Egg Tray Molding

We specialize in manufacturing high-performance plastic egg trays through advanced injection molding technologies. As a leading supplier of custom plastic components, we cater to poultry farms, egg distributors, food logistics companies, and agricultural packaging brands. Our services focus on delivering tailored plastic egg trays that optimize egg protection, stacking efficiency, and sustainability – from mold design to mass production and partial assembly.

Whether you need standard 6/12/30-egg trays or fully customized configurations, we provide solutions that balance cost, durability, and environmental compliance.

Key Structures & Customization Options

1. Tray Body Design

Cell Structure:

Custom Cell Sizes: Adapt to egg dimensions (small, medium, large, or jumbo eggs) with diameters ranging from 40mm to 55mm.

Reinforced Walls: Anti-crack design with 1.2–2mm wall thickness for impact resistance during transport.

Ventilation Holes: Precision-molded airflow slots (2–5mm) to prevent moisture buildup and ensure freshness.

Stackability:

Interlocking ridges on tray base/top for secure vertical stacking (up to 10 layers).

Optional corner reinforcements to prevent deformation under heavy loads.

2. Partition Walls & Grid Patterns

Flexible Layouts:

6-cell, 12-cell, 24-cell, or 30-cell configurations.

Modular designs for mixed-size egg packaging (e.g., 12 standard cells + 6 jumbo cells).

Material Optimization:

Honeycomb or ribbed grid patterns to reduce weight while maintaining structural integrity.

3. Edge & Handle Features

Ergonomic Handles:

Integrated grip slots or overmolded TPE handles for easy carrying.

Reinforced edges to prevent bending during manual handling.

Tamper-Evident Seals:

Optional snap-fit lids or shrink film attachment points.

4. Compatibility with Automation

Conveyor Belt Integration:

Flat-bottom designs for robotic pick-and-place systems.

RFID tag slots or barcode labeling areas for traceability.

Material Selection for Egg Trays

1. Polypropylene (PP)

Key Benefits:

Lightweight (density 0.9–1.1 g/cm³) with excellent chemical resistance.

Withstands repeated sterilization (up to 120°C) for reusable trays.

FDA-compliant for direct food contact.

Applications:

Reusable trays for industrial egg processing plants.

2. High-Density Polyethylene (HDPE)

Key Benefits:

High rigidity and moisture resistance, ideal for cold storage.

UV-stabilized options for outdoor transportation.

Applications:

Single-use trays for supermarkets or export logistics.

3. Polystyrene (PS)

Key Benefits:

Cost-effective for disposable packaging.

Smooth surface for easy labeling.

Applications:

Budget-friendly trays for local farm distribution.

4. Recycled & Bio-Based Materials

Options:

Post-Consumer Recycled (PCR) PP/HDPE: 30–100% recycled content, reducing carbon footprint.

PLA (Polylactic Acid): Compostable material for eco-conscious brands (suitable for short-lifecycle use).

Starch-Blended Polymers: Biodegradable alternatives with enhanced flexibility.

Certifications:

BPI, OK Compost, and EU 10/2011 compliance available.

Advanced Injection Molding Process

1. Precision Mold Design

Tooling Expertise:

Multi-cavity molds (up to 48 cavities) for high-volume output (10,000+ trays/day).

Conformal cooling channels to reduce cycle time by 20–30%.

Sliding cores and lifters for complex undercuts (e.g., handle slots).

Prototyping:

3D-printed prototype validation within 5 days.

2. Material Processing

Injection Parameters:

High-speed injection (clamping force 150–600 tons) for uniform wall thickness.

Gas-assisted molding for thicker ribs without sink marks.

Eco-Friendly Additives:

Antimicrobial agents (silver ions) for hygiene-critical applications.

Anti-static additives to repel dust in automated facilities.

Post-Molding Enhancements

Surface Treatments:

Texture etching (grit patterns) for anti-slip stacking.

In-mold coloring to eliminate post-painting.

Assembly Services:

Ultrasonic welding for attaching hinged lids.

Pad printing for batch numbers or logos.

We are plastic mold maker and can provide custom mold service, we can make injection molds, blow molds, rotational molds and die-casting molds.

For custom injection molds, we can provide professional custom injection molding services. Usually Plastic egg tray Molding are manufactured using injection molding technology. The mold materials for injection molds can be chosen from P20, 718, S136, H13 and so on. The mold material reflects the mold life and product material requirements.

For parts that require blow molding production, we can also provide professional custom blow molding services.

Mold design:

Information you need to provide us

1. If you have drawings, 2D drawings, 3D drawings (preferably in STEP format).

2. If there are no drawings, you need to provide specific length, width, height and weight information. (It’s best to send us samples)

3. Should the mold be sent to your country, or leave the mold in our factory and we will help you produce the product.

4. Mold material requirements, cavity number requirements (you can tell us about the size of your injection molding machine)

5. Product material requirements and product quantity. (You can tell us about the use of the product and we can give you suggestions)

Transaction process:

Mold testing:

Once the mold is complete, I do a mold test. It usually takes about 3-5 days to complete. We need to assemble the mold, adjust the pressure data of the machine, and try production. We need to check whether there are problems during the normal production of the mold and make modifications.
