• Minimalist texture and rounded corners bring ritual to takeout packaging, matching the refined tone of cafes and light meal shops.

Product Features & Advantages

Natural Cornstarch Base, Fully Biodegradable

Made from renewable cornstarch, unlike petroleum-based plastics, it fully decomposes into CO₂ and water in natural environments with no microplastic residues, truly realizing a “from nature to nature” circular lifecycle.

Food-Grade Safety for Versatile Ingredients

Complies with food contact safety standards, odorless and free of harmful substance migration. Safe for fresh produce, cold light meals, baked goods, cooked snacks and more, suitable for refrigerated and room-temperature scenarios.

Shallow Tray Design for Intuitive Display

20mm shallow height + large opening design ensures ample capacity while fully showcasing ingredients, enhancing visual appeal—perfect for ready-to-eat packaging and display in light meal shops and fresh food supermarkets.

Sturdy Load-Bearing, Resistant to Deformation & Leakage

Dense material structure balances toughness and hardness, resisting bending and deformation when holding fresh food or meals. Non-slip bottom texture enhances stability and prevents sliding and spills during transport.

Breathable & Moisture-Retentive for Extended Freshness

Micro-breathable cornstarch material moderately regulates internal humidity, delaying water loss in fruits/vegetables and spoilage of light meals, preserving fresh taste and appearance better than ordinary plastic trays.

Design Details

Non-Slip Bottom Texture Structure

The bottom of the tray features a dense interlocking grid texture, which increases friction with surfaces, packages or hands to prevent ingredient sliding, while reinforcing structural strength to avoid local collapse under load, enhancing overall stability and durability.

Reinforced Thickened Edge Craftsmanship

The perimeter edges are thickened for superior anti-bending performance, resisting deformation during handling and effectively preventing leakage caused by edge damage, thus improving safety and reliability.

Square Stackable Design

The classic square shape with a flat top allows stable multi-layer stacking, significantly saving storage, transportation and display space. It also ensures neat arrangement in takeout packaging to avoid tipping, boosting logistics and store operation efficiency.

Rounded Corner Safety Transition

Large rounded corners eliminate sharp edges that could scratch hands or packaging, ensuring safer use while softening the visual lines for a more refined and gentle appearance, ideal for premium light meal and fresh food packaging.

Lightweight High-Strength Structure

At only 20.5g per piece, the tray achieves lightweight design while maintaining sufficient load-bearing capacity and structural strength. This reduces overall packaging weight and logistics costs, aligns with low-carbon environmental concepts, and improves portability.

Shallow Tray Large-Opening Display Design

The 20mm shallow height and large opening provide ample capacity while fully exposing food to view, maximizing the visual presentation of ingredients and textures—perfect for light meals, fresh produce and baked goods that rely on visual appeal.

Micro-Breathable Material Property

The cornstarch-based material has inherent micro-porous breathability, which moderately regulates internal humidity to delay water loss in fruits/vegetables and spoilage of light meals, preserving freshness and taste better than traditional sealed plastic trays.
