FAQ
Q: What materials are your vacuum containers made of?
A: Our containers are made from high-quality borosilicate glass or BPA-free plastic, both certified for food safety. All materials meet international standards such as FDA and LFGB.
Q: How long can food stay fresh in your vacuum boxes?
A: With negative pressure vacuum technology, food freshness can be extended 3–5 times longer compared with regular storage. This helps reduce waste and keeps flavors intact.
Q: Are the containers microwave and dishwasher safe?
A: Yes. The glass series is microwave, dishwasher, and freezer safe (lids should be removed before heating). The plastic series is safe for refrigeration and washing, but not recommended for high-temperature cooking.
Q: How do I use the vacuum pump?
A: Simply place the pump valve on the lid and press or activate the pump. Within seconds, air is removed, creating a vacuum seal. Our electric vacuum pump provides faster, hands-free operation.
Q: What is your minimum order quantity (MOQ)?
A: For standard models, MOQ is one carton per item. For OEM/ODM projects, MOQ depends on customization requirements. Please contact us for details.
Q: How do you ensure product quality?
A: We operate modern production lines with strict quality control systems. Every batch undergoes testing for vacuum sealing performance, durability, and safety. Our factory is ISO9001, ISO22000, and BSCI certified.
Q: How are products packaged for shipment?
A: All containers are packed in protective cartons with shockproof materials to prevent damage during transport. Export packaging meets international logistics standards.
Q: What is your lead time?
A: Regular products can be shipped within 7–15 days. Customized orders usually require 20–30 days, depending on complexity and order size.
