A 390ml round food container is a compact packaging option for individual portions, side dishes, sauces, snacks, and small takeaway meals. Its nominal capacity is 390 milliliters, equivalent to 0.39 liters or approximately 13.2 US fluid ounces. The exact outside dimensions, usable fill level, lid fit, and material depend on the product design, so buyers should confirm a supplier’s specification sheet or sample before placing a bulk order.

This guide is for food brands, distributors, wholesalers, catering businesses, and packaging buyers comparing containers for commercial use. It explains what the capacity means, how to match the container to a product, and what to check when requesting a quotation. Zhengjia can discuss product specifications and sourcing requirements with buyers seeking a suitable food-container solution.
The 390ml figure refers to the container’s stated capacity, not necessarily the amount of food that should be packed to the rim. A product may need headspace to accommodate a lid, reduce spillage, or preserve appearance during handling. For products sold by weight, volume alone does not determine the portion weight because ingredients have different densities.
Ask the supplier how capacity is defined and whether it represents brimful volume or a recommended filling volume. Then test the actual food in a sample container using your normal filling method. This simple check helps avoid selecting a package that technically meets a volume target but does not suit the portion your customers expect.
Two containers can both be described as 390ml round food containers while having different diameters, heights, rim profiles, and lid designs. Those differences affect shelf presentation, storage, filling equipment, stacking, and compatibility with bags or outer cartons. Do not assume that capacity alone guarantees a fit with an existing lid or packing line.
For a reliable comparison, request the outside diameter, height, inside dimensions if relevant, rim design, and lid specification. Ask for a drawing or sample where precise fit matters. Zhengjia can review a buyer’s target dimensions and application when discussing an appropriate product specification.
Material selection should follow the food’s properties and the conditions the package will encounter. Plastic options used in food packaging can differ in clarity, stiffness, impact behavior, and suitability for particular filling or storage requirements. The material name alone is not enough to establish that a container is appropriate for every food or temperature condition.
Buyers may encounter materials such as polypropylene (PP) or PET in food packaging, but these should not be treated as interchangeable or assumed to be available in every design. Confirm the exact material and intended use with the supplier. If microwave use, hot filling, freezing, or contact with oily or acidic foods is required, state that requirement before sampling and request documentation appropriate to the application.
A 390ml round format can be considered for individual servings and compact food portions where the product’s shape and portion size fit the container. Possible applications include dips, dressings, cut fruit, desserts, side dishes, toppings, nuts, and prepared snacks. These are examples of potential uses, not a guarantee that one container design is suitable for every product on the list.
For sauces or dressings, evaluate closure fit and leakage performance under the handling conditions you expect. For salads, fruit, or chilled sides, consider visibility, headspace, and how condensation may affect presentation. For dry snacks, focus on closure, stackability, and whether the package protects the product during storage and transport.
Also consider where the container will be used: retail display, foodservice counter, meal delivery, or catering. A product that works well for stationary display may need different closure or handling characteristics for delivery. Match the sample test to the real workflow, including filling, closing, stacking, transport, and opening by the end user.

Record the food type, target serving weight or volume, texture, and any special handling requirements. Test the portion in the container rather than relying only on a catalog capacity. Leave suitable headspace where needed and check that the lid closes without pressing into the product.
Compare the container’s dimensions with your filling equipment, storage area, and secondary packaging. Confirm whether the lid is included, sold separately, or offered in more than one design. If you already use a lid or tray, request a compatibility check rather than assuming that similar-looking parts will fit.
Use a sample to assess filling, closing, handling, stacking, and appearance with your actual product. For delivery applications, test the packed item using a process that reflects your normal distribution conditions. Record any issues, such as difficult lid application or insufficient headspace, and have the supplier confirm the agreed specification in writing.
Request a quotation that identifies the material, capacity, dimensions, lid configuration, packing method, MOQ, and lead time. Ask which food-contact documents or other product records can be supplied for your intended market. Requirements vary by destination and use, so buyers should confirm the applicable obligations with their own compliance team or qualified adviser.
Unit price is only one part of the landed purchasing cost. The quoted amount may depend on material, container and lid configuration, order quantity, packaging, customization, and shipping arrangements. Ask suppliers to state clearly what the quotation includes and whether the lid, inner packing, or custom printing is priced separately.
MOQ and lead time are product- and order-specific, so obtain current figures rather than relying on general estimates. Confirm whether a sample or pre-production approval affects the schedule, and ask when the production lead time begins. For repeat orders, agree on how specification changes, forecast updates, and packaging details will be handled.
Customization can be useful when a buyer needs a specific appearance or brand presentation, but it may affect minimum quantities, cost, and scheduling. Before requesting artwork or tooling-related changes, establish which options the supplier can support for the chosen container. Keep the approved sample, drawing, and written specification aligned so that the purchase order describes the same product.
For a B2B purchase, clear records reduce avoidable misunderstandings. Keep the approved sample reference, specification sheet, quotation, and purchase-order description together. If the supplier proposes a substitute material or design, review and approve the change before production rather than treating it as automatically equivalent.
A 390ml round food container is a practical candidate for compact portions, but capacity alone does not determine whether it will work for your product. Confirm the usable fill level, dimensions, material, closure, application conditions, and market documentation before committing to a bulk order. The most effective next step is to define your food and packing requirements, request the relevant specifications, and evaluate a sample in your actual workflow.
When contacting Zhengjia, share your target application, required container and lid details, order quantity, destination market, and any customization needs. This information gives the supplier a clear basis for checking product suitability and preparing a quotation. Approve the sample and written specification before placing the production order.
