Choose a Bagasse Clamshell by SKU, Menu Fit and Carton Packing

Start With the Drawing Revision, Not the Inch Label

An inch label helps you find a product family. Your purchase specification needs more detail. Two boxes called “8 inch” can differ in base area, wall angle, lid height and locking geometry. Those differences decide whether your normal meal fits comfortably or needs rearranging before the lid closes.

Start with the bagasse clamshell range, then connect each shortlisted model to its drawing and sample. Use the container sample-testing guide to turn those dimensions into practical checks.

Identify the SKU and the Measurement State

Ask which product code the drawing covers, when it was issued and whether it shows the container open or closed. A long dimension across an unfolded clamshell cannot be treated as the closed box length.

Keep unfamiliar notation exactly as supplied until someone explains it. A slash between two measurements might refer to different heights or measurement states. Guessing its meaning can put the wrong dimensions into a purchase order.

Request a marked drawing showing the hinge, locking tabs, measurement points and tolerances.

Record the Space Your Food Can Actually Use

Your meal needs a flat supporting area, room below the rim and clearance under the lid. Rounded corners, sloping walls and dividers all affect that space.

For a burger, check the bun footprint and finished height. For a rice meal, check the portion in each well. Include wrappers, garnish and sauce cups. They travel with the food and belong in the fit test.

Keep Nominal, Measured and Approved Values Separate

Record catalog dimensions as nominal, sample readings as measured and the agreed purchase specification as approved. Attach the method and revision to each.

That small distinction makes later discussions easier: everyone can see which number was a starting reference and which number governs the order.

Compare Warmpack Clamshell Models With Clear Data Boundaries

Use a model comparison to narrow your options before requesting samples. The 8-inch clamshell and 9-inch three-compartment clamshell provide two relevant starting points for different meal layouts.

The following records combine clearly identified reference sources. They are a shortlist for confirmation, rather than an approved specification sheet.

Table 1. Warmpack Reference Models and Packing Fields to Confirm

Product dimensions and packing quantities for B003, B021 and BT026-1 come from the supplied reference specification table. B030 dimensions and the centimetre-labelled carton dimensions come from public product listings checked on October 15, 2026. Drawing revisions, usable capacity, carton gross weight and current supply status remain to be confirmed. Slash notation is preserved without interpretation.

Build a Shortlist Around One Menu

Select two plausible models and fill both with the same normal serving. Keep the recipe, portion weight and accessories consistent.

Smaller formats may suit compact foods, while larger formats offer another option for broader meal layouts. Let the filled comparison determine the choice. A larger inch number alone does not establish usable capacity or stronger handling performance.

Compare Single and Divided Formats

A single well offers flexibility for a composed meal. Dividers help organise separate components, but each well still needs enough usable space.

Compare the largest food component first. A fillet that fits a single compartment may sit awkwardly across a divider. Separately assess sauce movement during delivery; a divider does not automatically create a liquid-tight seal.

Resolve Packing Differences Before Approval

Published and reference records can differ. For B021, the website lists 45.5 × 37 × 22 cm, while the supplied table records 46 × 38 × 22 without stating carton units. BT026-1 also has differing records.

Ask Warmpack to issue one dated packing sheet for the chosen configuration. That sheet should connect the product, inner pack, carton quantity, dimensions and gross weight.

Validate the Filled Pack Before Choosing a Model

A drawing shows geometry. A filled sample shows how your kitchen and delivery process use it.

Follow a consistent sample-testing procedure, then connect the approved reference to the bulk-order quality-control checklist.

Agree on Food, Temperature and Holding Conditions

Write down the actual menu, portion weight, filling temperature, waiting time and delivery duration. Include stacking, transport bags and reheating or freezing requirements where relevant.

Choose demanding normal meals from your operation. A dry sandwich and a sauced rice meal place different demands on the same box. Test each intended use within the supplier’s documented conditions.

Avoid turning one successful sample into a performance promise for every food, configuration or temperature.

Check Closure, Handling and Stacking

Close the filled box using the normal packing motion. Check whether food touches the rim, presses against the lid or obstructs a locking tab.

Lift it as staff normally would, place it in the delivery bag and reproduce the agreed stacking arrangement. Record lid movement, base flexing, hinge damage, food displacement and any external moisture separately.

Use fresh samples for checks that would otherwise be affected by earlier handling.

Write Acceptance Criteria Before Testing

Replace “looks good” with observable criteria. For example, agree that the normal portion must fit below the closure area, the locking points must stay engaged during the defined delivery simulation and the filled base must remain adequately supported.

Set sample quantities, test duration and acceptable limits jointly. Record the date, model, configuration, results and photographs. An empty result field means testing is still pending.

Turn an Approved SKU Into a Carton Requirement

Once the meal fits and the sample is approved, translate demand into a packing requirement. The MOQ and mixed-SKU loading guide supports order planning, while the quotation comparison guide helps keep commercial comparisons consistent.

Confirm Inner Packs and Pieces per Carton

Ask how many containers sit in each inner pack and how many inner packs go into an export carton. Check the product count against the packing sheet.

Also define the quoted unit. Does one unit include the hinged container only? Are labels, sleeves, sauce cups or other accessories separate? Each item can affect cost and packing.

An integrated lid does not mean every accessory shown in a menu photograph is included.

Calculate Carton Counts and Geometric CBM

For whole-carton quantities:

Cartons = ordered pieces ÷ confirmed pieces per carton

For carton dimensions stated in centimetres:

Carton CBM = length × width × height ÷ 1,000,000

Then multiply carton CBM by the carton count. Keep units visible throughout the calculation.

Work Through a Conditional Packing Example

Suppose a new, approved B021 packing sheet confirms both 200 pieces per carton and 45.5 × 37 × 22 cm. For a planning quantity of 50,000 pieces:

• Carton count: 50,000 ÷ 200 = 250 cartons.

• Volume per carton: 45.5 × 37 × 22 ÷ 1,000,000 = 0.037037 m³.

• Total carton volume: 250 × 0.037037 = 9.25925 m³, approximately 9.259 m³.

This example depends on both packing fields being confirmed together. The reference sources currently differ, so the calculation does not approve that combination.

Geometric carton volume also does not establish carrier chargeable volume, pallet space or container loading capacity.

Confirm Mixed-SKU Minimums and Packing Revisions

Check minimums by model, colour, material and customisation. A combined order quantity does not automatically satisfy every SKU minimum.

If demand is not a full-carton multiple, agree on the order adjustment or packing arrangement. For mixed orders, obtain a carton schedule by SKU.

Recalculate when carton dimensions, nesting, inner packaging or pallet requirements change.

Match Materials and Documents to the Exact Configuration

A familiar model code is only part of the specification. Material, colour, barrier treatment and added components can affect the configuration you are approving.

Use the product catalog download to organise available product information, and request the relevant configuration documents for review.

Identify Fiber, Barrier, Color and Accessories

List the declared fibre composition, colour and any coating or barrier treatment. Identify separate components such as windows, labels, sleeves or sauce cups.

Ask whether a proposed change affects dimensions, closure, handling, packing or the documents already reviewed. A sample approval should describe enough detail for production to reproduce the agreed configuration.

Terms such as “natural colour” or “bagasse” alone do not define every material or component.

Review What Each Document Actually Covers

Review food-contact information, PFAS-related testing and compostability documentation as separate items. Check product identification, formulation, manufacturing site, intended conditions, market scope and applicable validity.

For a test report, check what was measured and under which method. For a certificate, check the product scope and status.

Keep outstanding questions visible. A document associated with one factory or product family should not be assumed to cover every colour, barrier or accessory combination.

Send a Model-Specific Sample and Quotation Brief

A useful inquiry gives the supplier enough detail to recommend and price the same configuration your team intends to approve.

Use the price and MOQ comparison guide when comparing quotations. For freight, destination charges and other cost categories, refer to the landed-cost guide.

Use a Shared Approval and RFQ Record

Keep the sample plan, results and purchasing fields together. A shared record helps the kitchen, purchasing team and supplier work from the same version.

Table 2. Sample Approval and RFQ Record

Separate Approval, Production and Transport Milestones

Ask what starts the production lead time: approved samples, artwork, deposit or another agreed event. Record the planned production completion and dispatch separately from transit and customs estimates.

For repeat orders, refer to the approved sample and packing revision. If a relevant specification changes, assess whether new samples or document review are needed before production proceeds.

Buyer FAQs

1. Which drawing dimensions belong in my purchase order?

Reference the SKU, drawing revision, measurement state, critical dimensions and agreed tolerances. Attach the approved drawing so abbreviated descriptions do not create competing interpretations.

2. Can two clamshells with the same inch size use the same carton?

That requires confirmation. Nesting geometry, hinge shape and inner packing can differ. Obtain a packing sheet for each model instead of transferring carton data between similar names.

3. How should usable capacity be measured for a divided box?

Define the fill line and method, then measure each compartment where relevant. Record temperature and required lid clearance. Keep measured usable capacity separate from nominal or brimful capacity.

4. How do I choose between an 8-inch and a 9-inch model?

Pack the same meal into both. Compare food placement, lid clearance, closure and delivery results. The 8-inch model and 9-inch divided model are useful candidates to discuss.

5. Does one quoted unit mean a complete meal-packaging set?

Ask for an itemised definition. A hinged box may be one unit, while a sleeve, label, sauce cup or cutlery pack is quoted separately.

6. Can different sizes share one order minimum?

Ask Warmpack to confirm minimums by SKU and configuration. Mixed loading and production minimums are separate purchasing questions.

7. Which measurements are needed for a freight estimate?

Provide carton length, width, height and units, gross weight, carton count, destination and delivery terms. Include pallet dimensions and restrictions if palletisation applies.

8. What should trigger another sample approval?

Review changes affecting fit, materials, closure, performance or packing. Record the decision and use the quality-control checklist to connect production checks to the approved reference.

9. Does a compostability document cover every option?

Check its scope against the exact product and configuration. Fibre colour, barriers and added components should be reviewed where relevant to the document’s coverage.

10. Can Warmpack supply from a US warehouse?

Ask for written confirmation of the current supply location and available models. A US destination or distributor inquiry does not establish local inventory.

Request a Drawing and Sample Plan

Send your selected SKU or menu brief, portion size, filling and delivery conditions, quantity by model, destination and required documents.

Ask Warmpack to confirm the drawing, packing revision and sample plan before issuing the final quotation. Start with the clamshell product range, then contact Warmpack with your project details.
