Import Bio-Based 3cp Foam Container Food Box — Buy in wholesale FOB from Supplier in China

Laizhou Guoliang Packing Co., Ltd. produces a bio-based three-compartment clamshell food box from polylactic acid, a polymer derived from fermented plant starch rather than petroleum feedstocks. The container measures 6 inches by 6 inches by 3 inches or 9 inches by 9 inches by 3.3 inches, with additional sizes available, and is designed for hot and cold food service applications including sandwiches, salads, sushi, and fried items. The PLA material offers a heat deflection temperature typically between 50 and 60 degrees Celsius, making it suitable for warm service but not for microwave reheating or oven applications above that threshold.

The clamshell construction uses embossed forming to create rigidity without added material weight, and the three-compartment layout separates main items, sides, and condiments to reduce cross-flavour contamination during transport. PLA is certified industrially compostable under EN 13432 and ASTM D6400 when processed in controlled high-temperature composting facilities; it does not biodegrade efficiently in anaerobic landfill or marine environments. The material density is approximately 1.25 grams per cubic centimetre, providing structural stability comparable to conventional polystyrene foam at a slightly higher unit weight. Thermal insulation properties are moderate, so delivery times and ambient temperatures during distribution should be planned accordingly.

This product targets food service distributors, chain restaurants, catering companies, and institutional meal programmes seeking petroleum-free packaging with visible sustainability positioning. Custom logo printing is available, and orders from 100,000 pieces are accepted, though production capacity and lead time are not stated in the source data. Buyers should confirm composting certification validity, migration testing for food contact compliance, and whether the supplier holds BRC, ISO 22000, or equivalent quality management accreditation. Incoterms, port of shipment, and payment structures require direct negotiation with Laizhou Guoliang Packing Co., Ltd.

Laizhou Guoliang Packing Co., Ltd. operates from Hutouya Industrial District in Laizhou City, Shandong Province, China, postal code 266000. The company is positioned within one of China's denser clusters of plastic and packaging manufacturing, with access to raw material suppliers and mould fabrication services. The supplier holds a harbor trust tier, indicating basic platform verification without additional third-party audit confirmation. The response rate is recorded at 0.00 percent with zero average response hours, suggesting minimal or no active inquiry history rather than a measurable service record.

The listing carries the Guoliang brand name and states acceptance of custom orders with logo printing, implying in-house or contracted decorating capability. No information is provided about factory size, number of employees, annual turnover, export licence details, years in operation, or existing major clients. There is no mention of food contact safety certifications such as FDA, EU 10/2011 compliance documentation, or quality management systems like ISO 9001 or ISO 22000. Buyers should conduct independent verification of manufacturing standards, request factory audit reports, and confirm regulatory compliance documentation before committing to volume orders.
