For a custom jute bag, specify the inside as carefully as the outside. A bonded film, a sewn fabric lining and a base insert are different components. Choose them around the intended contents and presentation, then compare complete samples. None should be assumed from a product photograph or the words “natural jute”.
1. Separate lamination, lining and base support
In your brief, use lamination for a layer bonded to the fabric, lining for a separately made inner fabric layer, and base insert for a component supporting the bottom. Ask the supplier to confirm the actual construction rather than relying on these names alone. A lined version can also contain laminated fabric; identify each layer and its purpose separately.
| Component | Specify | Check on the sample |
|---|---|---|
| Bonded film | Material identity, side, coverage and attachment to the jute | Creases, exposed edges and separation |
| Fabric lining | Fibre, colour, coverage, seam and top-edge attachment | Usable space, lifting and contact with contents |
| Base insert | Material, dimensions, thickness and fixed or removable design | Movement, corner fit and support with the intended contents |
2. Match the inside to the product and its contents
LinHord’s cotton-rope tote and faux-bamboo tote provide two shopper references. For boxed gifts, compare how the interior meets the box corners and whether the base remains presentable when lifted. For clothing, inspect contact surfaces, exposed seam edges and ease of removing the garment. Specify the experience you need before requesting additional layers.
For the window jute wine bag, any proposed lining must preserve the intended label view. Show where it stops around the window and how it meets the base. Review the actual closed bottle and any divider together. Lamination, lining, inserts and dividers discussed here are options to request for feasibility review, not confirmed standard features of these catalogue products.
3. Specify the layer and its attachment
Request a material swatch showing both faces and a section or drawing naming every layer. Record the film material if proposed, coverage at the top fold, and whether seams expose untreated jute. For a fabric lining, agree its finished dimensions, attachment points and whether a pocket belongs to the same version. Ask for photographs of the inside before final approval; a front view cannot settle these details.
If bond strength is part of the requirement, ask a laboratory whether ISO 2411:2024, a coating-adhesion method for coated fabrics, applies to the proposed material. Agree preparation and acceptance requirements with the laboratory. A method name is not evidence that a particular bag has been tested.
4. Keep water resistance and material claims specific
If moisture exposure matters, describe the actual situation: occasional splashes, a damp exterior, or contact with a chilled closed bottle. Ask what evidence addresses that situation. ISO 1420:2016 concerns water penetration through coated fabrics under specified hydrostatic pressure and time. Such fabric evidence does not by itself establish leakage performance at sewn seams, a window joint or an open top.
Check customer-facing material wording against the whole construction. For US marketing, the FTC Green Guides summary cautions against broad environmental claims and requires evidence for compostability claims covering all materials. Natural jute alone does not establish the status of an added film, adhesive, lining, handle or insert.
5. Compare the finished versions before approving
Compare the proposed versions using the same bag dimensions and actual contents, keeping other changes recorded. Photograph each sample empty, filled, carried and unpacked. Inspect the following points, then retain the approved version and its layer specification through sample approval. Do not turn a visual comparison into a load rating or cleaning instruction.
- Look inside the corners and top fold for loose material, exposed edges or unwanted gathering.
- Insert and remove the actual contents; check lining movement and remaining usable space.
- Repack using the proposed method and review creases, insert position and window visibility afterwards.
6. Send an RFQ that identifies the complete version
- Product reference, intended contents, finished size and required inside clearance.
- Separate decisions for bonded film, fabric lining and base insert, including “none” where intended.
- Layer materials, attachment drawings, window boundaries and fixed or removable components.
- Sample comparisons, packing method, agreed checks and evidence for any performance wording.
- Logo brief, quantity per style and colour, destination and required delivery date for quotation review.
Send the brief through the LinHord RFQ form. Bulk MOQ is 100 pcs per style per colour; colours cannot be combined to meet the minimum. Sampling arrangements, construction feasibility and timing are confirmed after review.
