How to Specify a Delivery Paper Bag That Will Not Tear at the Bottom

A paper bag that fails under a two-person takeaway order is usually being specified as a shopping bag rather than as a delivery system. Start with the real packed load, then define the bag footprint, base construction, handle attachment, resistance needed for the food and delivery conditions, and a pass/fail transport test. Do not approve a bag from paper weight alone.

For two mains, two drinks, and side dishes, make a sample pack exactly as a customer would receive it. Record:

• the combined weight of food, drinks, containers, cutlery, and sauces;
• the outside dimensions and base footprint of the packed containers;
• whether drinks travel inside the bag or separately;
• how long hot food stays in the bag before handoff and during delivery;
• where the previous bags failed: centre of the base, a bottom seam, a corner, or a handle patch.

The bag needs a margin above the normal packed weight because a courier lifts, swings, sets down, and may stack the order. The most useful purchasing target is therefore a tested working load for your packed order, not a claim that a bag is simply “strong.”

Bottom tears are often a geometry and seam problem. A bag that is too narrow makes containers lean or concentrate their weight on a fold. A flat or block-bottom format with a base that fits the containers lets the load sit more evenly.

Put these items in the RFQ:

1. **Internal width, gusset, and height.** Give the supplier the dimensions of the packed meal set and require the containers to sit flat without forcing the side walls outward.
2. **Bottom format.** Request a flat, block, or self-opening-square base appropriate for the footprint. Ask the supplier to identify the bottom folds and glued seam arrangement in the sample.
3. **Base reinforcement options.** If the failure is at the base, compare a heavier base, reinforcement patch, double-layer construction, or another suitable construction—not just a heavier bag everywhere.
4. **Seam requirement.** State that there must be no opening, paper split, or glue release after the agreed transport test.

A larger bag is not automatically safer. Excess empty space lets containers shift; an undersized bag loads the corners and bottom folds. The right base is one that supports the order with minimal movement.

The handles transfer the whole order load into a small area near the top of the bag. Specify the handle type, where it is attached, and the reinforcement at the attachment point. Then test it as assembled, not as a loose component.

Ask the supplier to provide samples with the intended handle construction and to show the attachment area. In your acceptance test, lift the loaded bag repeatedly, carry it one-handed and two-handed, and include a controlled swing or movement that reflects handoff to a courier. Reject any sample with handle pull-through, tearing around the attachment, or a top edge that starts to split.

Paper basis weight can be a useful comparison point, but it does not prove that a bag will survive a hot, oily delivery order. Heat and condensation can soften paper; oil can migrate into folds and seams. Tell the supplier what the bag will carry: hot containers, fried food, sauced dishes, cold drinks, or a combination.

Request the relevant material and performance information for the intended bag, including how it performs after folding and when exposed to the expected heat, steam, and grease. If you need food-contact, PFAS-free, compostability, recyclability, or other compliance claims, ask for documentation that applies to the exact material, construction, SKU, order, and destination market. Do not convert a general material description into a product-wide claim.

Laboratory information is useful, but a representative packed-order test is the decision point. Run the same comparison across each candidate bag:

1. Pack two mains, two drinks, and sides at normal serving temperature.
2. Close and load the bag as staff would during a busy shift.
3. Carry it, lift it, set it down, and move it through the time and handling expected in delivery.
4. Check the base, seams, corners, handles, and any area exposed to moisture or grease.
5. Photograph failures and note the load, delivery time, weather or condensation conditions, and exact failure location.

Test more than one sample from each option. A bag should pass only when it retains its shape and contains the order without a bottom rupture, seam opening, or handle failure under the agreed test conditions.

**Application:** Delivery paper bag for a two-person takeaway set: two mains, two drinks, and side dishes. **Packed-order data supplied:** Total packed weight, container dimensions, drink placement, and expected delivery duration. **Required format:** Bag base must fit the packed containers so they sit flat with limited movement. Please state the internal dimensions, gusset, bottom construction, seam arrangement, paper specification, handle type, and handle reinforcement. **Food conditions:** Please confirm suitability information for the actual hot, steamed, oily, or sauced food conditions described in the enquiry. **Sample and test:** Provide samples for a loaded transport test using our representative order. The acceptance criteria are no bottom tear, seam opening, handle detachment, or loss of containment after the agreed test. **Documents:** Provide only the material, food-contact, and environmental documentation that applies to the proposed product, order, and destination market.

Compare like for like. Put dimensions, base construction, paper/material description, handles, print requirements, carton packing, sample availability, documentation scope, and the test plan in one comparison sheet. A lower unit price is not comparable if the supplier has quoted a different base, handle, or material construction.

For a custom order, also approve the digital artwork and written specification before production. Keep the signed-off sample, specification, and test record with the purchase order so that later deliveries can be checked against the same standard.

If you are developing a branded delivery bag, TakeawayPack can discuss the bag structure, material, dimensions, print requirements, and destination details as part of an RFQ. Final suitability, MOQ, production terms, and any documentation should be confirmed for the specific product and order. Start the conversation at takeawaypack.com with your packed-order dimensions, photos of the current failure, and the transport test you want the sample to pass.
