A plastic storage box is a versatile, durable, and eco-friendly storage solution widely used in household food preservation, industrial material organization, catering and food delivery, and office supplies classification. As a professional plastic storage box manufacturer and OEM plastic storage box manufacturer, we have been deeply engaged in plastic manufacturing since 2016. With our advanced production base and a global network spanning over 90 countries, we are committed to producing high-quality, environmentally friendly plastic storage box products. We utilize food-grade PP material and precision injection molding processes to ensure that every plastic storage box delivers excellent temperature resistance (-20°C to 120°C), reliable leak-proof sealing structure, and convenient stackable design, meeting the comprehensive needs of different customers for safety, practicality, and economic efficiency.
As a China plastic storage box manufacturer with over a decade of industry experience, every product we produce undergoes strict food contact material safety certification. Below are the core technical specifications of our plastic storage boxes:
| Parameter | Specification |
|---|---|
| Material Type | Food-grade PP plastic, BPA-free |
| Temperature Range | -20°C to 120°C (Freezing to Microwave Heating) |
| Sealing Grade | Leak-proof sealing design, 360-degree surround locking |
| Structural Design | Stackable nesting, portable lightweight design |
| Reusability | Reusable for more than 50 cycles |
| Environmental Attribute | 100% recyclable, compliant with food contact material regulations |
| Customization Service | OEM/ODM supported, covering 90+ export regions |
As an experienced China plastic storage box manufacturer and OEM plastic storage box manufacturer, we understand that material selection is the core factor determining product quality. Our factory is equipped with advanced automated production equipment, with an annual capacity of tens of millions of units. All products have passed food contact material safety certifications and are supported by a comprehensive quality traceability system. Food-grade PP (polypropylene) plastic has become the industry's material of choice for plastic storage boxes due to its excellent heat resistance, chemical stability, and mechanical strength. Unlike disposable PS material, PP contains no plasticizers and will not release harmful substances during microwave heating, ensuring the safety of stored items.
For scenarios requiring microwave heating functionality, such as microwaveable containers and products from a microwave-safe plastic food container factory, strict control of the material's temperature resistance is essential. PP material has a melting point of over 160°C and performs stably in microwave heating environments below 120°C without deforming or releasing odors. In addition, sealing design is another critical technical indicator. High-quality leak-proof lids typically adopt a silicone sealing ring combined with a snap-fit structure to achieve 360-degree surround sealing, effectively preventing liquid leakage and odor escape.
From a full life-cycle cost perspective, although reusable plastic storage boxes have a higher initial procurement cost, after more than 50 uses, their per-use cost becomes significantly lower than that of disposable storage boxes. As an industry-leading enterprise continuously investing in R&D resources, we are committed to developing more environmentally friendly and durable products. According to industry calculations, one reusable storage box can replace approximately 100 disposable containers during its lifetime, reducing carbon emissions by over 60%.
| Comparison Dimension | Reusable Plastic Storage Box | Disposable Storage Box |
|---|---|---|
| Usage Count | 50-100 times | 1 time |
| Temperature Resistance | -20°C to 120°C, microwave-safe | Typically 0°C to 70°C, not microwave-safe |
| Sealing Performance | High (Precision snap + sealing ring) | Medium-Low (Simple locking) |
| Structural Strength | High, drop-resistant and compression-resistant | Low, easily deformed and damaged |
| Environmental Impact | Waste reduced by over 90% | Generates large amounts of plastic waste |
| Applicable Scenarios | Household, catering, industrial, retail | Temporary events, short-term use |
A: Yes. The plastic storage boxes we produce are made from food-grade PP material with a temperature range of up to 120°C, fully meeting microwave heating safety requirements. As a professional microwave-safe plastic food container factory, every process from raw material procurement to finished product delivery strictly adheres to ISO quality management system standards. However, it is recommended to remove the lid or loosen the snaps during heating to avoid steam pressure buildup. Also, avoid heating high-oil or high-sugar foods for extended periods to prevent localized overheating.
A: Replacement is recommended when the following conditions occur: obvious scratches or whitening on the container surface; loose lid snaps resulting in poor sealing; container deformation preventing stable stacking; or usage has exceeded 50 cycles. Regular inspection ensures storage safety and sealing performance.
A: The scope of application is very broad, including: cooked food leftovers, dry goods and snacks, frozen ingredients, fruits and vegetables, industrial parts, and office stationery. Food-grade material ensures food safety, while damage-resistant structure adapts to industrial environments. For liquid foods, it is recommended to control the fill level to no more than 80% of the container capacity for optimal sealing performance.
A: Yes. As a professional OEM plastic storage box manufacturer, we provide comprehensive customization services, including size specifications, color matching, LOGO printing, partition design, and packaging solutions. We have complete mold development capabilities and can quickly produce samples according to customer requirements. Currently, our products have been exported to over 90 countries and regions, accumulating rich cross-border cooperation experience.
A: It is recommended to clean promptly after use. They can be washed in a dishwasher using a high-temperature program (placed on the top rack), or hand-washed with neutral detergent. For commercial usage scenarios, it is recommended to use high-temperature steam disinfection or UV disinfection cabinets to ensure compliance with food safety and hygiene standards. Avoid using hard cleaning tools such as steel wool to prevent scratching the surface and affecting service life.
