Designed for premium kitchenware and lifestyle brands, this round stainless steel food container collection combines durable SUS 304/316 steel construction with transparent tempered glass lids and flexible silicone frames. Built with a space-saving nesting architecture, the system allows smaller units to fit seamlessly into larger containers, optimizing both warehouse shipping efficiency and end-user storage.

Stainless steel construction provides a hygienic, stain-resistant, and non-porous alternative material platform for brands developing modern food-storage collections.

Key Design & Architecture Features

1. Nesting Multi-Size Architecture

The precisely engineered round dimensions enable full nesting across the size matrix.The nesting architecture helps reduce packing volume and storage footprint across multi-size sets.

2. Transparent Tempered Glass & Silicone Frame

Unlike traditional opaque metal containers, the heat-resistant tempered glass lid allows direct visibility of stored contents without opening the container. The surrounding food-grade silicone frame ensures a snug lid fit while providing shock absorption for daily use.

3. SUS 304 / SUS 316 Material Platform

Choose between high-grade SUS 304 for general kitchenware applications or premium SUS 316 for enhanced corrosion resistance. Both material options present a clean, brushed metallic finish suitable for contemporary home and lifestyle retail lines.

4. Customizable Color System for Private Label

Customize the silicone lid frames with brand-specific Pantone colors to create cohesive seasonal collections or matching kitchen sets.

(Note: Exact capacity and wall thickness can be customized according to client project specifications.)

Microwave Compatibility & Validation Framework

Microwave-Compatible Product Configuration

For projects requiring microwave suitability, specific validated models and material configurations are available. Microwave performance depends on precise container geometry, rim curvature, lid handling, and operating conditions.

• Approved Operating Power: Max 700W (Project specific protocol)

• Heating Duration: Max 3–5 minutes per cycle (Depending on food load)

• Lid Instructions: Remove or unseal the glass/silicone lid prior to microwave operation as instructed by project safety guidelines.

• Placement Requirement: Center the container inside the microwave cavity with minimum 2 cm clearance from inner metal walls.

• Empty Container Restriction: Do NOT heat empty stainless steel containers in microwaves.

• Validation Documentation: Model-specific laboratory test protocols and arcing evaluations are available upon project scope confirmation.

Component-Specific Use & Care Guidelines

To maintain long-term performance and surface integrity, components should be handled according to their respective material guidelines:

• Stainless Steel Body: Suitable for freezer storage, standard ovens (up to 220°C / lid removed), and dishwasher cleaning. For microwave heating, follow validated project configurations only.

• Tempered Glass Lid: Oven and dishwasher safe within approved thermal limits (-20°C to 150°C thermal shock threshold).

• Silicone Frame: Dishwasher safe; keep away from direct oven heating elements or open flames.

• Surface Finishes / Decorative Coatings: Hand washing recommended for electroplated or color-coated exterior surfaces to extend coating longevity.

Procurement & B2B Logistics Parameters

Quality Control & Testing Protocol

Every OEM production run undergoes structured inspection across five core stages:

1. Material Verification: PMI / spectrometer testing can be used to verify the stainless steel grade against the approved SUS 304 / SUS 316 specification.

2. Food-Contact Testing: Silicone and glass components can be evaluated according to applicable target-market food-contact requirements and the approved project scope.

3. Dimensional & Nesting Inspection: Dimensional tolerance checks verify nesting fit, dimensional consistency and surface clearance.

4. Lid Fit & Sealing Evaluation: Testing lid seating, silicone gasket tension, and leak-resistance under standard fill conditions.

5. Thermal & Microwave Validation: For microwave-designated SKUs, samples undergo arcing and heating cycle evaluations under standardized test protocols.

6. Packaging & Drop Testing: Standardized carton evaluate packaging performance against the agreed transport/drop-test requirements. during international ocean/air transport.

Frequently Asked Questions

Q1: Can stainless steel food containers really be used in a microwave? A1: Yes, under specifically engineered container geometries, smooth rim designs, and controlled power/time parameters. We offer microwave-compatible configurations that have undergone testing protocols. Please consult our team for verified SKU lists and detailed operating instructions.

Q2: Are these containers available as nesting retail sets? A2: Yes. The round collection is designed specifically to nest together (S into M into L into XL). We can pack multi-size sets into a single retail color box for direct sale.

Q3: What is the difference between SUS 304 and SUS 316 options? A3: SUS 304 is the industry standard for food storage, offering excellent durability and rust resistance. SUS 316 contains added molybdenum, providing superior corrosion resistance against high-salt or high-acid food preparations.

Q4: Can we customize the color of the silicone frame and lid? A4: Yes, we provide custom Pantone color matching for silicone frames, as well as laser-etched or stamped brand logos on the steel body or glass lids.

Q5: Can the glass lid stay on during microwave heating? A5: We recommend removing or unsealing the lid assembly during microwave heating to allow steam dissipation to allow steam release and support more even heating under the approved use conditions.

Q6: What testing documentation is available for export projects? A6: Material analysis reports for SUS 304/316, food-contact testing documentation for silicone/glass components, and factory ISO audits are available based on project requirements and agreed scope.
