Custom Paper Bag Sourcing: Sizes, Materials, Printing and Samples

1. Define finished dimensions and intended contents

Write width × depth × height and label the measurement order. State whether the dimensions are for the finished bag and whether the handle is excluded from height. If you know only the size of the contents, share that information and ask for a proposed bag size to sample.

• Measure the product, any inner packaging and the space needed to insert or remove it.
• Describe the expected contents and normal carrying weight; ask how the proposed construction will be checked.
• Agree measurement tolerances instead of assuming every bag will have identical dimensions.

2. Specify paper and handle construction separately

Name the paper type, colour and any required paper weight. Weight alone does not establish load capacity: the paper, folds, adhesive, reinforcement and handles work together. Ask the supplier to identify the proposed construction rather than approving it from an image.

• For handles, describe twisted paper, flat paper, rope, die-cut or another required style.
• Confirm reinforcement where needed, especially around handles and the base.
• Ask for applicable evidence if you require certified paper or a particular recycled content; a claim in a listing is not confirmation for your order.

3. Identify the exact print and artwork revision

State which sides are printed, the number of colours, the approximate coverage and any finish. Label the artwork version and ask the supplier for its required file format and print area. Clarify whether a colour reference is for visual guidance or an agreed production target.

• Ask whether printing plates, setup or artwork preparation are charged separately.
• Review logo placement, margins and folds on the supplied dieline or proof.
• Use an appropriate physical sample to assess print and material; a screen proof does not show their real appearance.

4. Split the quantity by size and design

Give a total quantity and the breakdown for each size, colour and artwork. The minimum shown on a general listing may not apply to custom printing. Ask whether the custom-order minimum is per design or across the order, and whether any overrun or underrun allowance is proposed.

5. Request an itemized quotation and sample plan

Request the unit price and currency at your exact quantity, together with sample fees, setup costs, packing and delivery terms. Ask what type of sample is offered and which features would differ from production. A sample-fee refund should remain unknown until the supplier confirms its conditions in writing.

• Record sample lead time and production lead time separately, including when each starts.
• Ask for pieces per carton, carton dimensions and gross weight before assessing freight.
• Confirm the named delivery location and excluded costs, plus how long the quote is valid.

6. Approve the physical sample against the specification

Check the actual product fit, dimensions, handle attachment, base, paper feel and print. Test normal handling appropriate to the intended contents. Record the agreed tolerances and approved sample revision so a future inspection has a reference. A good sample is useful evidence, but does not by itself establish consistent bulk production.

Example: one design, two bag sizes

This is an illustrative specification, not a supplier offer or a tested packaging recommendation. Change the dimensions and load requirement for your own products.
