Start with the job the bag has to do
A bag name is useful, but it does not describe the whole job. Two customers may both ask for a flat bag while packing products with very different weights, edges, storage conditions and filling methods. A better enquiry begins with the product: what goes inside, how much goes into each bag, what happens during filling and where the packed item goes next.
Write down the target fill weight or volume, the product’s approximate dimensions and whether its shape changes after filling. Dry ingredients may settle into the bottom of a bag. A bulky retail item may press against the sides. A product with firm corners may put stress on a different area. These ordinary details give the supplier something concrete to discuss.
The packing process matters too. State whether staff fill by hand or use existing equipment, how the opening is closed and whether the customer will open the bag once or many times. Explain if the packed bags are stacked, carried individually or placed into an outer carton. If an existing bag stretches, tears or sits badly on the shelf, describe when the problem appears. That is more useful than asking for a “stronger” bag without context.
Top Ten Plastics has made plastic bags in Ipoh, Perak since 1993, so our plastic bags page shows the formats within the range we produce in-house. Use it to identify a likely direction, then support that choice with a written brief.
Match the format to filling and display
Flat bags keep the construction straightforward and may suit products that do not need much room around their sides. A centre-seal or side-seal direction changes where seams sit in relation to the contents and the printed face. These positions can affect filling, presentation and where important artwork can be placed.
A gusset gives the contents space to expand into a fold. That can help with a bulkier filled shape, but the gusset must be included in the measurements and artwork discussion. A stand-up base is relevant when the pack needs to sit upright for display. Test the idea with the actual filled shape rather than assuming that the base alone will make every product stand evenly.
A resealable closure can make sense when customers use only part of the contents at a time. It also occupies space near the opening, so it affects usable capacity and the area available for seals or print. If the product is normally emptied in one use, the added feature may not solve a real need.
Record dimensions so they cannot be misread
“Width by length” may be enough for a simple comparison, but many bags need more explanation. Record whether the dimensions describe the empty bag laid flat or the bag after filling. Mark the opening, seals, folds, gussets and closure position. If print orientation matters, add an arrow showing which edge is the top.
For an existing bag, measure it flat and provide clear photographs with a ruler or marked sketch. A physical sample is even better when available. The sample still needs written notes because it cannot show the planned order quantity, contents, target fill or any change you want to make.
For a new product, start with the product dimensions and the amount placed in each bag. Allow for the way the contents settle and for the space needed to close the opening. Overfilling can make sealing awkward or place pressure on the bag. Too much spare room can leave the pack looking loose and may use more material than the job requires.
Ask both sides to repeat the dimensions in the same order on the quotation and proof. A small labelled drawing often prevents more confusion than a long email.
Describe storage and handling conditions
The bag continues working after it leaves the filling table. Note whether it will be stored at room temperature or chilled, whether it may meet moisture or oil, and how long packed stock normally waits before sale or use. Mention any rough edges on the contents and any repeated movement during delivery.
Avoid treating one material label as a complete performance specification. Construction, dimensions, seals, filled weight and handling work together. A useful discussion connects the proposed bag to the actual conditions rather than promising that one material direction suits every product.
When replacing a failed bag, keep a sample if practical and record whether the issue appeared during filling, sealing, transport or customer use. This narrows the discussion without pretending that a photograph proves the cause.
Plan printed bags around approved artwork
Printed packaging needs controlled files. Give each design a clear name and version, and identify which quantity belongs to it. If you send both editable artwork and a PDF reference, label the final files so an older draft is not mistaken for production artwork.
Check the visible information before approval. Product names, contact details, barcodes, instructions and other required copy should be reviewed by the business responsible for the product. The proof confirms the intended layout, but approval should never be treated as a substitute for reading every word and number.
Seals, folds, gussets and closures can interrupt the printable area. Finalise the bag format and dimensions before locking the layout. Also mark which way the design should face during filling and on display. A technically upright file can still appear upside down if the opening and front face were understood differently.
Colour on a phone or office monitor is not a dependable physical reference. Tell the supplier early if a colour is important, and ask what the applicable proof is meant to confirm. Material and print conditions affect appearance, so the approval conversation should be specific rather than based on how a screen happens to look.
If the design is still being tested or several versions are needed in smaller quantities, read the guide to digital printing for small runs before committing to a larger printed order.
Give quantity and timing real context
A quotation needs a realistic expected quantity. “As low as possible” does not explain whether the job is a trial, a monthly repeat or stock for a seasonal campaign. Give the quantity per size and per artwork version, then state how firm the number is.
Share the target delivery period and the date by which artwork or final quantities will be ready. Production timing depends on the complete job, not only the day the first enquiry was sent. A bag specification that is still changing should be treated differently from a repeat order with approved information.
Think about stock risk as well as unit price. Buying more printed bags may be unhelpful if product details, branding or demand could change. On the other hand, an unrealistically small request may not suit the proposed format or production route. The supplier needs the honest use case to explain the practical options.
For repeat work, quote the previous job reference and confirm what remains unchanged. Do not assume that saying “same as last time” covers a new artwork file, quantity or delivery arrangement. A short change list makes the handover easier to check.

Frequently asked questions
Which plastic bag format should I ask for?
Begin with the contents, filled shape and packing process. Flat, centre-seal, side-seal, gusseted, stand-up and resealable formats suit different jobs. You do not need to settle the name before enquiring. Send a sample or sketch, then explain how the bag is filled, closed, displayed and handled. Those details help narrow the direction without treating the format name as the full specification.
What measurements should be included?
Provide the empty bag's flat width and length, plus any gusset, seal, fold or closure measurements. Mark the opening and print orientation. For a new bag, add the target fill weight or volume and the filled product dimensions. A labelled drawing is useful because it shows exactly where each number begins and ends. Photographs should support the measurements, not replace them.
Can a supplier copy my current bag?
A current bag is a useful reference, especially when paired with written dimensions and a description of its use. It may not reveal every construction detail, tolerance or process condition. Explain what must stay the same and what you want to change. The proposed quotation, proof and approved job information should become the working reference rather than relying on an unlabelled sample alone.
What information affects price and timing?
Format, dimensions, intended contents, quantity, print coverage, number of designs, artwork readiness, finishing and the required delivery period all affect the discussion. List quantities by size and design. State whether the request is a trial or repeat order and whether the date is fixed. Top Ten Plastics can then identify missing details before the job is treated as ready for production.
