Q1: What materials are used in this food storage container set? Are they 100% plastic-free?
Answer: Yes, our containers are completely plastic-free and eco-friendly. The body and the lid are both made of high-borosilicate glass (or premium tempered soda-lime glass, Note: choose based on your actual line), and the sealing gasket is made of 100% food-grade LFGB/FDA silicone. It is an ideal sustainable alternative to traditional plastic-lid containers.
Q2: What food safety certifications do your glass containers and silicone lids hold?
Answer: Our products strictly comply with international food contact regulations. We provide certified test reports including FDA (US), LFGB (Germany), EU Framework Regulation (EC) No 1935/2004, and BPA-Free certifications. All testing is conducted by third-party agencies like SGS or TUV. Certificates can be provided upon request before bulk ordering.
Q3: Can the glass lid be used in the oven and microwave along with the container?
Answer:The Borosilicate Glass Container & Lid: Both can withstand temperatures up to 400°C (752°F) and are 100% safe for oven and microwave use.
The Silicone Seal: The food-grade silicone ring can withstand up to 220°C (428°F). However, for microwave heating, we recommend loosening the lid to allow steam to escape; for oven baking, we advise removing the silicone ring to prolong its lifespan.
Crucial Specification: The thermal shock resistance is 120°C (248°F), meaning it can safely go from the refrigerator directly to a preheated microwave.
Q4: How effective is the silicone seal? Is it 100% leak-proof and airtight for liquid food?
Answer: Yes. Our glass-on-glass design features a custom-engineered, multi-ridge silicone gasket that creates a 100% airtight and leak-proof vacuum seal. It prevents food oxidation, locks in moisture, and eliminates any risk of spills during transportation, making it perfect for meal prep, soups, and sauces.
Q5: Is the silicone seal removable for cleaning? Does it get moldy over time?
Answer: The silicone gasket is designed to be fully removable for deep cleaning and is 100% dishwasher safe. Because we use premium, non-porous food-grade silicone with high hydrophobic properties, it resists bacteria growth and mold, provided it is dried after washing.
Q6: Can we customize the shape/size of the glass container and the color of the silicone rim?
Answer: Absolutely. We offer full OEM/ODM services.
Silicone Rim: Can be customized to any Pantone color code (MOQ applies).
Logo Printing: We support high-temperature decal printing or laser engraving on the glass lid/body, as well as embossed logos on the silicone seal.
Custom Molds: We have an in-house R&D team to open custom molds for proprietary sizes and shapes.
Q7: What kind of packaging do you use for bulk shipping to prevent breakage?
Answer: Breakage control is our top priority. For B2B bulk export, we use:
Drop-test approved packaging: Individual bubble wrapping or egg-crate corrugated dividers.
Retail Packaging: Custom color boxes with molded pulp or EPE foam inserts for Amazon FBA sellers.
Master Carton & Palletization: Heavy-duty 5-layer export cartons secured with corner protectors and pallet wrapped with stretch film to ensure a breakage rate below 1% during sea freight.
Q8: What is your Minimum Order Quantity (MOQ) and standard lead time?
Answer:For stock items/standard sizes: Our MOQ starts from 1,000 pcs per size.
For custom colors or printing: The MOQ is typically 3,000 pcs.
Lead Time: Mass production usually takes 30 to 45 days after sample approval and deposit receipt, depending on the order volume and customization details.
Q9: Do you support FOB/CIF/DDP shipping terms? Can you ship directly to Amazon FBA or regional distribution centers?
Answer: Yes, we support flexible Incoterms including FOB Shenzhen/Ningbo/Qingdao (Note: choose your port), CIF, and DDP. We have extensive experience working with freight forwarders for seamless delivery to Amazon FBA warehouses (including FBA labeling and pallet compliance) and large retail distribution chains in North America, Europe, and South America.
FAQ: High-Performance Glass Lid Focus
Category 1: The Plastic-Free & Thermal Revolution (Lid vs. Plastic Lids)
Q1: What makes your glass lid superior to traditional plastic (PP/TPE) container lids?
Answer: Unlike conventional plastic lids that distort, leach chemicals, or crack under extreme temperatures, our Plastic-Free Tempered Glass Lid with Integrated Silicone Rim is engineered for maximum thermal and environmental performance. It is 100% plastic-free, chemical-free (BPA, BPS, and Phthalate-free), and will not stain or absorb odors. It allows consumers a truly sustainable, zero-plastic food storage experience from preparation to serving.
Q2: Can the glass lid REALLY go directly into a preheated oven along with the container?
Answer: Yes, absolutely. This is our core technical advantage. Both the tempered glass lid and the high-grade silicone seal are completely oven-safe up to 220°C (428°F). You can bake, roast, or reheat food in the oven with the lid securely on, which retains food moisture and prevents oven splatters. Traditional plastic lids will melt instantly under these conditions, but our all-glass-and-silicone lid remains structurally perfect.
Category 2: Extreme Temperature & Convenience (Freezer to Microwave)
Q3: Is the lid safe for long-term deep freezing? Will the seal crack in the freezer?
Answer: Yes. The entire product—including the glass container, the tempered glass lid, and the food-grade silicone seal—is engineered for extreme blast freezing and deep freezer storage (down to -40°C / -40°F). While standard plastic lids become brittle and prone to snapping at freezing temperatures, our silicone-sealed tempered glass lid maintains its elasticity and structural integrity, ensuring a tight frost-free seal.
Q4: How do I use this product in the microwave? Do I need to remove the lid?
Answer: For ultimate convenience, you can place the entire container with the glass lid still on directly into the microwave. Unlike plastic lids that risk warping or releasing harmful microplastics under microwave heat, our glass lid is 100% microwave-safe.
Pro-Tip for Users: Simply rest the lid loosely on top or unclip it slightly to allow steam to escape while heating. This keeps your microwave 100% clean from food splashes while speeding up the heating process uniformly.
Category 3: Sealing Performance & Commercial Longevity
Q5: Does the glass-on-glass weight affect the airtight sealing performance?
Answer: It actually improves it. The natural weight of the tempered glass lid combined with our precision-engineered, multi-groove silicone rim creates a superior downward-pressure seal. This yields a 100% airtight, leak-proof, and spill-proof vacuum barrier that excels at locking in freshness, preventing freezer burn, and preserving liquid contents better than lightweight, warping plastic snap lids.
Q6: What is the lifespan and durability of this lid compared to plastic clip lids?
Answer: Our tempered glass lid with silicone rim offers more than 3x the operational lifespan of traditional plastic lids. Plastic clips and hinges frequently snap after repeated bending or degradation from heat and oils. Our lid features no moving plastic parts that wear out, making it an incredibly durable investment for premium kitchenware brands, retailers, and eco-conscious consumers.
