Sustainability is no longer just a buzzword — it’s reshaping how we grow, package, and deliver food.
As governments and retailers push to reduce plastic waste, PLA (Polylactic Acid) trays have become one of the most practical and eco-friendly alternatives to traditional plastic packaging.
At Sequoia Enterprise Ltd., we manufacture biodegradable PLA trays, salad boxes, and clamshell containers designed for fresh fruit and vegetable packaging.
If you’re considering switching to PLA for your salads, tomatoes, or produce line, here’s everything you need to know — from performance and safety to storage and cost efficiency.
1. What Makes PLA Trays Different from Traditional Plastic Trays
PLA (Polylactic Acid) is a bioplastic made from renewable resources such as corn starch or sugarcane.
Unlike conventional plastics (like PET or PP) that are derived from fossil fuels, PLA is plant-based, biodegradable, and industrially compostable.
Core Characteristics:
-
Renewable Origin: Derived from crops — not petroleum.
-
Eco-Friendly Disposal: Breaks down into CO₂ and water under composting conditions.
-
Food Safe: Certified under FDA and EU 10/2011 standards.
-
Crystal Clear Appearance: Excellent transparency for product visibility.
-
Compatible with Thermoforming: Easy to mold into salad trays, fruit boxes, and clamshells.
This combination of eco-performance and clarity makes PLA a preferred choice for companies seeking eco-friendly packaging without sacrificing appearance or quality.
2. Why PLA Trays Are Ideal for Salads, Tomatoes, and Fresh Produce
2.1. Breathability That Keeps Produce Fresher
Unlike airtight plastic containers, PLA trays allow controlled oxygen exchange, preventing condensation and spoilage.
This is especially important for delicate produce like tomatoes, lettuce, berries, and grapes, which need ventilation to stay crisp and fresh.
Sequoia’s vented PLA trays and lids are designed to balance airflow — maintaining the natural look and taste of fresh food throughout transportation and storage.
2.2. Excellent Transparency for Retail Display
Consumers buy with their eyes.
PLA’s glossy, glass-like transparency enhances the natural color of fruits and salads, improving shelf appeal in supermarkets and grocery stores.
Sequoia’s PLA trays are available in clear and semi-clear options, suitable for branding, labeling, and barcode scanning.
2.3. Lightweight and Durable Design
PLA trays are lightweight yet rigid, reducing overall packaging weight while maintaining structural integrity.
They resist cracking under stacking pressure — an essential feature for fresh produce transportation and bulk display.
2.4. 100% Compostable — Certified Green Packaging
All Sequoia PLA trays meet EN 13432 and BPI compostability standards.
This means the entire tray — including the film and lid — can be industrially composted, supporting zero-waste initiatives in retail and hospitality sectors.
2.5. Temperature Suitability
PLA performs best in cold or ambient conditions (−20 °C to +50 °C), making it perfect for chilled salad bars, tomato packaging, or cold storage logistics.
For high-temperature applications, Sequoia also offers modified PLA blends with improved heat resistance up to 70 °C.
3. Common Applications in Fresh Food Packaging
| Product Type | Recommended PLA Packaging | Key Benefits |
|---|---|---|
| Salads & Ready Meals | PLA salad bowls and lids | Hygienic, transparent, compostable |
| Tomatoes & Cherry Tomatoes | Vented PLA trays or clamshell boxes | Prevents condensation, extends freshness |
| Berries & Grapes | Perforated PLA fruit boxes | Lightweight, breathable, high visibility |
| Mixed Vegetables | PLA rectangular trays | Stackable, secure sealing, customizable size |
| Fresh Herbs & Microgreens | PLA mini trays | Sustainable packaging for premium produce |
Sequoia’s products are designed for automated packing lines, ensuring compatibility with sealing machines, labeling systems, and shrink wrapping.
4. The Sustainability Advantage
Switching from petroleum-based plastic trays to PLA offers measurable environmental benefits.
| Environmental Metric | PLA | PET / PP (Conventional Plastic) |
|---|---|---|
| Raw Material Source | Renewable (plant-based) | Non-renewable (fossil fuel) |
| CO₂ Emissions | 60–75% lower during production | High emissions |
| End-of-Life | Compostable under industrial conditions | Landfill or incineration |
| Toxicity | Non-toxic, BPA-free | Potential microplastic generation |
| Recycling Compatibility | PLA waste stream | Mixed contamination risk |
By using PLA trays, producers and retailers can reduce their carbon footprint, achieve green certifications, and strengthen their sustainability image in global markets.
5. Challenges and How Sequoia Solves Them
5.1. Heat Resistance
Traditional PLA softens around 60 °C.
Sequoia addresses this with enhanced PLA resin formulations, offering improved thermal resistance and greater structural rigidity during sealing and transport.
5.2. Moisture Sensitivity
PLA performs best in dry, refrigerated conditions.
Sequoia’s packaging designs include micro-vented lids and optimized tray geometries to prevent water accumulation and maintain freshness for moisture-sensitive produce like tomatoes and lettuce.
5.3. Cost and Supply
While PLA was once more expensive than conventional plastic, growing global production has stabilized prices.
With Sequoia’s high-volume manufacturing and OEM/ODM customization, clients can now enjoy cost-efficient, sustainable packaging at scale.
6. Certifications and Food Safety Compliance
All Sequoia PLA trays meet international standards:
-
EN 13432 & BPI Certified Compostable
