Product Description

Designed for established kitchenware brands, food storage importers, and lifestyle retailers, this stainless steel storage platform combines the hygienic durability of 304 stainless steel with the functional clarity of a vented tempered glass lid. Engineered across 9 standardized capacities in rectangular, square, and round formats, the modular body profile allows compact nesting and secure lid-on stacking in refrigerator shelves and kitchen cabinets. The integrated silicone rim provides a snug closure fit, while the top silicone vent button enables controlled steam release during ambient pressure changes.

 Component Specifications & Boundary Matrix

To ensure accurate consumer product labeling and operational safety, each material component carries specific thermal and environmental use boundaries:

*Thermal Note: Stainless steel container body is designed for conventional oven, freezer, and refrigerator use. For any microwave application, explicit client-side testing and local regulatory compliance validation must be confirmed per finalized SKU configuration.

 Standard SKU & Assortment Architecture

We offer 9 standard SKUs across three geometric shapes, supporting flexible mixed-SKU assortment programs for retail box sets or open-stock collections:

*Note: Net weights, steel sheet gauge, and master carton packing quantities are specified per finalized technical order sheet.

 Closure Mechanism & Seal Performance Validation

Lid seating and closure performance are evaluated under defined structural and pressure conditions rather than generalized marketing claims:

• Integrated Silicone Rim Sealing: The perimeter silicone rim wraps securely around the tempered glass center, creating a firm friction fit against the smooth 304 stainless steel curled rim to prevent odor crossover and moisture loss during chilled storage.

• Functional Pressure Relief Vent: The integrated silicone vent button allows warm air and steam to escape before sealing, preventing lid vacuum locking during temperature changes in the refrigerator.

• Seal Evaluation Protocol: In-factory quality checks verify lid closure retention with the vent button fully depressed under standard ambient and chilled storage conditions.

 Quality Control & Material Compliance Framework

Every production batch undergoes structured physical, chemical, and dimensional inspection across all three material components:

• 304 Stainless Steel Body QC: Material grade verification (XRF spectroscopy check for 18/8 Cr-Ni content), wall thickness uniformity, rim curling finish (ensuring smooth, burr-free edges), and deep-drawing surface defect inspection.

• Tempered Glass Lid QC: Thermal shock testing, impact resistance verification, edge smoothness, and optical transparency inspection.

• Silicone Rim & Vent Fit Check: Precise dimensional alignment between the tempered glass edge, silicone rim channel, and stainless steel body to ensure smooth engagement and proper vent button sealing.

• Food-Contact Compliance: 304 stainless steel, tempered glass, and silicone raw materials are specified to comply with international food-contact safety standards (e.g., U.S. FDA, EU 1935/2004, and Germany LFGB heavy metal and overall migration guidelines). Full testing reports are coordinated based on the finalized product configuration.

• Transit Packaging Engineering: Given the combination of metal bodies and glass lids, master carton layouts utilize EPE foam partitions or corrugated dividers to pass drop and vibration evaluations prior to shipment.

Frequently Asked Questions

Q1: What capacities and shapes are available in this stainless steel collection?

A: The platform includes 9 standard SKUs across three shapes: 7 Rectangular sizes (420ml, 750ml, 800ml, 820ml, 1200ml, 1600ml, 1800ml), 1 Square size (640ml), and 1 Round size (690ml).

Q2: What are the specific material components of the container and lid?

A: The container body is manufactured from 304 food-grade stainless steel. The lid consists of a tempered glass viewing window encased in a food-grade silicone perimeter rim with a top-mounted silicone steam-release vent button.

Q3: Which components are safe for oven, freezer, and dishwasher use?

A: The 304 stainless steel body is safe for conventional oven (up to +250°C / +482°F), freezer, and dishwasher use. The tempered glass lid with silicone rim is safe for refrigerator storage and dishwasher cleaning. Always remove the lid prior to oven heating.

Q4: How does the silicone vent button function?

A: The silicone vent button releases warm air pressure when closing the lid on warm food, allowing a snug seal without creating a vacuum lock. Pressing the button down seals the air vent for refrigerator storage; pulling it up disengages the seal for easy lid removal.

Q5: Can the silicone rim color and branding be customized for private label programs?

A: Yes. The perimeter silicone rim and vent button can be customized to any Pantone color (MOQ 3,000 pcs). We also offer laser engraving on the stainless steel body, screen printing on the glass lid, and custom retail box packaging.

Q6: What food-contact compliance documentation can be provided?

A: Raw materials (304 stainless steel, tempered glass, and food-grade silicone) are selected to meet major international food-contact guidelines, including FDA and LFGB migration standards. Official test reports are coordinated per finished SKU order configuration.

Q7: What are the Minimum Order Quantities (MOQ) and production lead times?

A: Base MOQ is 2,000 pcs per SKU, with flexibility for mixed-SKU container load programs. Standard sample lead time is 3–5 days, while mass production requires 35–45 days following sample approval and deposit confirmation.

Q8: How are multi-size containers packed for export shipping?

A: Containers are packed with protective interlayers or individual polybags into reinforced master cartons. EPE foam partitions or custom retail gift boxes are available for DTC mail-order or retail store fulfillment.
