B2B procurement · Buyer guide A private label toilet paper supplier should test the actual finished multipack seam, not only a heat-sealed strip made from loose film. Agree the seam location, specimen width, grip method and failure categories, then sample packs from different cartons before and after an agreed handling trial. The seal must stay closed in distribution while still opening without damaging the rolls. This is a buyer packaging test design. No Sansheng pack-seal value or destination-market compliance result is claimed. ASTM F88/F88M-23 measures seal strength of suitable flexible barrier materials; it does not set a toilet-paper multipack pass level.

Agree the seam location, specimen width, grip method and failure categories, then sample packs from different cartons before and after an agreed handling trial. The seal must stay closed in distribution while still opening without damaging the rolls. ## Identify every seam that matters Record film construction, seal pattern, overlap, pack count, roll size and artwork position. Mark end seams, longitudinal seams and opening tabs separately. The private label toilet paper supplier should include the finished pack geometry because roll compression and film tension may change seam loading. Keep an approved pack for visual and opening comparison. ![Wrapped toilet paper multipacks beside a loose roll](https://tissuepapersupplier.com/wp-content/uploads/2026/09/ss-07-private-label-toilet-paper-sku-exit-body-1.webp) *Illustrative image: Different pack counts can change film tension around seals.* ## Measure force and failure mode Cut or prepare test strips from production-intent multipacks under one agreed procedure. ASTM F88/F88M-23 measures the force required to separate a seal strip and identifies failure mode when the flexible-material scope applies. Report individual readings, specimen width, grip arrangement and whether the film tears, stretches or peels at the bond. A strong number alone may hide destructive opening. ![Open cartons holding wrapped toilet paper multipacks and loose rolls](https://tissuepapersupplier.com/wp-content/uploads/2026/09/ss-07-private-label-toilet-paper-sku-exit-body-2.webp) *Illustrative image: Case placement should be recorded before an arrival comparison.* ## Repeat after case handling Sample packs from different case positions and compare them with unhandled controls. Use the buyer’s planned stacking and transport challenge, then inspect for open corners, film tears and shifted rolls before retesting selected seams. Separate poor seal formation from package deformation caused by excessive wrap tension or carton pressure. ![Toilet paper rolls, multipacks and a clear film roll on a packing table](https://tissuepapersupplier.com/wp-content/uploads/2026/09/ss-07-private-label-toilet-paper-sku-exit-body-3.webp) *Illustrative image: Keep loose rolls separate from wrapped packs when diagnosing seam failure.* ## Set a usable release window Agree a lower bound for distribution integrity and, where hand opening matters, an upper bound or use trial. Define a hold rule for any open seam, not only the average force. Reapprove when film, seal temperature, dwell, jaw pattern, roll count or pack geometry changes. Retain failed packs with batch and carton IDs. ## Buyer comparison record | Check | Record | Buyer purpose | | --- | --- | --- | | Seam map | End, side and tab locations | Sample the right areas | | Strength | Individual force and failure mode | Judge bond behavior | | Handling | Case position and exposure | Check arrival risk | | Use | Opening without roll damage | Avoid over-sealing | ## Sansheng product evidence and its limits The linked Sansheng page identifies the relevant product or material context.

No. The pack also has to open without tearing the wrap unpredictably or damaging rolls. ### Can a loose-film heat seal approve a finished pack? No. Finished roll geometry and handling load the seam differently. ### Does seal strength measure film tension? No. Record film tension and roll shape as separate packaging checks. ## Sources and scope notes - [ASTM F88/F88M-23](https://store.astm.org/f0088_f0088m-23.html) **Supports:** Seal-strength measurement and failure mode for suitable flexible materials. **Limit:** Does not prescribe a toilet-paper multipack limit. - [Sansheng toilet paper product page](https://tissuepapersupplier.com/toilet-paper-supplier/) **Supports:** Identifies finished toilet-paper pack context. **Limit:** Does not provide this article’s seal results.
