Two wet toilet paper formats sit at opposite ends of the convenience-retail spectrum, and the choice between them is a channel decision before it is a factory decision. S01 is a 100-sheet wet toilet paper pack at 130 × 200 mm, produced on biodegradable wood pulp non-woven fabric. S02 is a 10-sheet wet toilet paper pack at 150 × 200 mm, produced on wood pulp cloth that can be disintegrated. Both are manufactured as custom wet toilet paper by Dalian Weijie Biotechnology Co., Ltd., a hygiene products manufacturer established in 2013 in Dalian, Liaoning Province, China, whose range also covers baby wipes, pet wipes, kitchen wipes, functional wipes and floor cleaning wipes, and whose retail-facing products appear under the sunfans brand.

The practical answer for everyday convenience brands is not "which model is better" but "which pack belongs on which shelf". S01 carries the economics of a bulk shelf pack: 100 sheets per unit, a 130 × 200 mm sheet, and a substrate described as biodegradable wood pulp non-woven fabric, listed by the manufacturer for large department stores and the personal care products industry. S02 carries the economics of a small-format pack: 10 sheets per unit, a 150 × 200 mm sheet, and a wood pulp cloth that can be disintegrated, listed for large retail chains, the general merchandise industry and home cleaning.

Problem Definition: Why S01 vs. S02 Is a Channel Decision Before It Is a Spec Decision

The sourcing problem for a convenience brand is not a shortage of wet toilet paper suppliers. It is that two formats with very different unit economics get treated as interchangeable because both are, technically, wet toilet paper. A sheet counts and dimensions look like minor line items in an enquiry; in retail they decide the price point, the shelf position, the pack weight and the reorder rhythm.

Two failure modes appear repeatedly in this category. The first is placing a heavy, high-count pack into a travel, personal-carry or impulse listing, where a 100-sheet unit cannot compete with a lighter format on pack price. The second is placing a small, low-count pack into a supermarket or department-store aisle where shoppers compare value, and where a 10-sheet unit reads as a sample rather than a routine purchase.

Because packaging artwork, pack dimensions, aroma selection and piece-count all flow from the format decision, the format is also the most expensive decision to reverse later. Buyers who settle S01 versus S02 first tend to reduce revision cycles on artwork and specification sheets, and they can brief their retail partners with a defined pack rather than a format family.

Industry Background: Where Wet Toilet Paper and Flushable Formats Are Growing

Wet toilet paper sits inside two markets that are both expanding but driven by different buyer logic. The global wet wipes market was valued at approximately USD 32.09 billion in 2026, with a projected CAGR of 3.86% reaching USD 43.45 billion by 2034, according to Fortune Business Insights. Within that total, personal care wipes held a 72.81% market share in 2025, based on Mordor Intelligence data.

The flushable and disintegrating segment is smaller but faster. Global Market Insights valued the flushable wipes market at USD 2.3 billion in 2025 and projected USD 4.2 billion by 2035 at a 6% CAGR. Plant-based flushable wipes were valued at USD 2.9 billion in 2024 with an expected 5.3% CAGR, and the broader biodegradable wipes market passed USD 3 billion in 2024, with growth attributed to baby wipes and premium retail segments. That combination — a flushable format plus a degradable substrate — is exactly the space S01 and S02 occupy.

Regional demand shapes which format sells where. The United States accounted for 34% of global wet wipes market share in 2024, while Japan accounts for nearly 27% of the Asia-Pacific wet wipes market with a strong focus on hygiene and premium quality personal care — relevant for suppliers already exporting to Japanese retail. Structurally, the category is led by large consumer groups: Procter & Gamble held over 12% of the global wet wipes market in 2025, and Kimberly-Clark held over 17.2% of the flushable wipes segment in 2025. For a private-label brand, that concentration is the opportunity: the formats are established consumer habits, and the differentiation happens at pack level.

The Two Formats, Spec by Spec

S01 — Wet Toilet Paper, 100 Sheets, 130 × 200 mm

S01 is specified as a 100-sheet wet toilet paper with a sheet size of 130 × 200 mm, produced on biodegradable wood pulp non-woven fabric. Its listed applicable industry is the pet products industry alongside large department stores and the personal care products industry. The 100-sheet count is what makes S01 a shelf pack rather than an impulse item: it supports a value-led price point and a slower reorder cycle, and it fits listings where the shopper expects a usable quantity per purchase.

S02 — Wet Toilet Paper, 10 Sheets, 150 × 200 mm

S02 is specified as a 10-sheet wet toilet paper with a sheet size of 150 × 200 mm, produced on wood pulp cloth that can be disintegrated. Its listed applicable industry is the home cleaning industry, large retail chains and the general merchandise industry. The sheet is wider than S01's — 150 mm versus 130 mm, with both formats sharing a 200 mm length — while the pack itself is deliberately small at 10 sheets, which is the profile of a travel, trial or personal-carry unit.

What the Difference Means for Packaging and Flushability

Sheet count drives pack presentation. A 100-sheet pack requires a format that can stand or hang on a supermarket or department-store fixture and carry full front-panel branding; a 10-sheet pack is naturally suited to compact, travel-friendly or counter-top display. Because the manufacturer's customization scope covers packaging, logo, material, size, aroma and number of pieces, both formats can be re-specified for a channel rather than accepted as fixed catalogue items.

Substrate wording matters just as much. S01's specification emphasises the biodegradability of the wood pulp non-woven substrate; S02's specification describes a wood pulp cloth that can be disintegrated. For a brand whose shoppers care about disposal behaviour, that distinction is the starting point for both the on-pack messaging and the destination-market review — and it is the point at which buyers should confirm the applicable labelling and disposal requirements with the manufacturer and their compliance team rather than assuming the same claim fits both SKUs.

Step-by-Step Breakdown: How to Select Between S01 and S02

1. Fix the channel and the purchase occasion first. A supermarket or department-store listing and a travel or personal-carry listing imply different pack sizes. Decide the shelf before comparing specifications.
2. Match sheet count to the purchase cycle. S01's 100 sheets support a routine household buy; S02's 10 sheets support a smaller, more frequent or single-occasion purchase. Sheet count is the single clearest divider between the two models.
3. Check sheet dimensions against intended use. S01 is 130 × 200 mm and S02 is 150 × 200 mm. If the pack is positioned for cleaning tasks where coverage per sheet matters, S02's wider sheet is the relevant parameter.
4. Read the substrate description against disposal expectations. S01 uses biodegradable wood pulp non-woven fabric; S02 uses a wood pulp cloth that can be disintegrated. Align the SKU with what your market actually asks about — biodegradability or disintegration.
5. Cost the pack with MOQ, lead time and customization in one model. The line is quoted with an MOQ of 20,000 yuan package, a 30-day lead time and monthly capacity of 3 million packages, with packaging, logo, material, size, aroma and piece count all customizable.
6. Verify compliance and export documentation before the order. Confirm certificate coverage (ISO 9001 and MSDS), destination-market rules for the target country, and the after-sales support available for verifying packing lists and customs declaration documents.

Use Cases: Supermarket Bulk Packs vs. Travel-Friendly Packs

Supermarket and Department-Store Programs — S01

S01's listed applicable industry includes large department stores and the personal care products industry, which is consistent with a bulk-pack placement: a 100-sheet unit at 130 × 200 mm gives the retailer a clear price point per pack and a lower pack-to-shopper friction than a small format. Brands building a large-pack custom wet wipes line or a bulk pack custom wet wipes listing generally start here, because the format already matches the shelf expectation for volume.

Travel, Personal Use and General Merchandise — S02

S02's listed applicable industry includes large retail chains, the general merchandise industry and home cleaning. A 10-sheet pack with a 150 × 200 mm sheet fits travel kits, personal-carry sets and counter-top or checkout displays, and it is the format to specify when a custom flushable toilet wet wipes SKU needs to feel portable rather than warehouse-scale. For brands testing a new market, it also lowers the entry pack size before committing to a large-pack program.

Evidence from Long-Running Retail Supply Programs

Format decisions are easier to defend when the supplier already ships at retail scale. The manufacturer's wider wet wipes program has supplied retail stores including 7-Eleven in Japan, as well as e-commerce and Lotte clients, with a three-year supply relationship at 15 40-foot containers per month. Longer relationships in the same program include a baby and maternity brand owner for five years at 20 40-foot containers per month, a major household and personal care conglomerate for eight years at 10 containers per month, a 150-year-old conglomerate for ten years at 10 containers per month, a top Amazon.com seller of pet supplies for six years at 8 containers per month, and a leading Amazon.com seller of baby products for four years at 8 containers per month. Customer feedback across these programs centres on stable quality over the long term and continuous new product proposals — the two things a convenience brand needs when it runs S01 and S02 as a pair.

FAQ: S01 and S02 for OEM and Private-Label Buyers

Conclusion: Which Format Should Your Brand Stock First?

If your first listing is a supermarket, department-store or personal-care shelf that needs a value-led, high-count pack, S01 is the starting format: 100 sheets, 130 × 200 mm, biodegradable wood pulp non-woven fabric, listed for large department stores and the personal care products industry. If your first listing is a travel, personal-carry or general-merchandise program that needs a light pack and a wider single sheet, S02 is the starting format: 10 sheets, 150 × 200 mm, wood pulp cloth that can be disintegrated, listed for large retail chains and the general merchandise industry.

Most convenience brands do not choose once. The two formats are complementary, and the same customization levers — packaging, logo, material, size, aroma and number of pieces — make it possible to run S01 as the volume SKU and S02 as the portable SKU inside one private-label range, against a shared MOQ basis of 20,000 yuan package, a 30-day lead time and a monthly capacity of 3 million packages. With retail supply experience in Japan, the United States, Australia, Canada, Singapore and Southeast Asia, and a long-running retail and e-commerce customer base, the format decision is a shelf decision your supplier can support either way.
