Product Description
Product Overview

The SUNMORE ROTO 30L Non-Partition Rotomolded Insulated Storage Box is a heavy-duty container manufactured using an integral seamless rotational molding process. Constructed from thickened food-grade LLDPE raw material in a single forming operation, this box features a large-capacity integrated storage space without internal partitions.

Equipped with dual stainless steel spring latches and a full surrounding rubber sealing strip, the box delivers excellent waterproof, dustproof, and heat preservation performance. Ideal for long-distance cold chain catering transportation, kitchen raw material storage, and outdoor equipment protection.

This 30L non-partition insulated box is widely used in catering canteens, food delivery cold chain, restaurant back kitchens, outdoor construction equipment storage, and industrial parts turnover. We provide comprehensive OEM customization services including exterior color, surface silk-screen branding, external handle structures, and internal insulation foam thickness according to customer specifications.

Key Features & Benefits
One-Piece Seamless Construction

Integral rotational molding without splicing gaps creates a smooth inner cavity with no separating baffles, maximizing the 30L internal volume for bulk storage. Thickened rounded corners resist collision and abrasion during stacking.

Food-Grade LLDPE Material

Made from environmentally safe food-contact LLDPE plastic that is odorless and harmless. Special modified formula maintains stable toughness across -30℃ to 60℃ temperature range, providing impact resistance and UV protection for long-term indoor and outdoor use.

Secure Sealing System

Dual heavy-duty stainless steel latches lock the lid tightly while integrated elastic rubber sealing strip completely blocks water vapor, dust, and temperature loss, ensuring stable thermal performance and waterproof protection.

Hollow Insulation Design

Hollow double-wall construction can be filled with PU foam for enhanced thermal insulation, effectively slowing temperature changes of internal contents to meet cold chain transportation requirements.

Full Customization Options

Complete OEM customization available for box body color, silk-screen logos, external side handles, and foam insulation thickness to suit specific catering and industrial storage applications.

Great value for money. Compared with other brands, SUNMORE's molds have longer service life and more reasonable prices. We plan to expand our order quantity next time.
