Short answer: ONePcDRY OD01 and My A+ PD01 are both baby diapers built on a full 100% SAP paper core made by Quanzhou ERA Sanitary Products Co., Ltd., but they are not interchangeable in one size ladder. OD01 runs from NB to XL with hot air super soft top and back sheets and Ammonia Removed 3D technology. PD01 starts at size M and extends to XXL with a crotch elastic design, anti-rash oil lines and a super soft clothlike breathable spunbond back sheet. Buyers who need newborn and small-size coverage build the line on OD01; buyers expanding toddler and plus-size coverage extend it with PD01.

The Problem: Two Full-SAP Cores, Two Different Size Ladders

The decision between OD01 and PD01 looks like a core-technology question, but it is usually decided earlier, at the size ladder. PD01 is available in M, L, XL and XXL. OD01 is available in NB, S, M, L and XL. That single difference means the two models cannot replace each other in the same shelf plan: PD01 cannot serve a newborn program at all, and OD01 cannot extend a range into XXL.

Three practical risks follow from choosing the wrong one:

• Size-ladder gap. A retailer lists NB and S because the store sits next to a maternity ward or a pharmacy counter. If the buyer commits to PD01 as the only line, those two sizes cannot be supplied from that model.
• Comfort-spec mismatch. OD01 leads with hot air super soft top and back sheets plus Ammonia Removed 3D technology. PD01 leads with a crotch elastic design, anti-rash oil lines and a clothlike breathable spunbond back sheet. The two models answer different consumer complaints.
• Re-specification cost. Changing a core specification after artwork, bag sizes and shelf plans are locked in means new sampling, new print and a new launch window.

Because both models share the same core architecture family, the choice is not about dryness versus dryness. It is a decision matrix question: which size ladder, which comfort architecture, and which absorbency brief does the program actually need.

Industry Background: Why Core and Fit Decisions Carry More Weight in 2026

The global baby diapers market was valued at approximately USD 83.3 billion in 2025 and is projected to reach USD 141.8 billion by 2033 (Grand View Research). Asia Pacific accounted for 61.92% of that market in 2025, generating approximately USD 50.01 billion (Fortune Business Insights). Within China's export base, Fujian Province accounts for 63.9% of total baby diaper exports, with an export value reaching 8.74 billion yuan in 2024 (Xiamen Customs / Jiayue). The premium diaper segment is projected to grow at a 7.2% CAGR through 2027, outpacing conventional products (Intel Market Research).

Two signals in that data matter for a buyer comparing two models from one factory. First, premium and differentiated products are where the growth rate sits, which pushes specification decisions — core composition, topsheet type, elastic design — into the centre of the buying conversation rather than the packaging conversation. Second, regulation is tightening: baby diapers placed on the EU market must comply with REACH, which restricts over 1,900 hazardous substances, and many brands additionally follow OEKO-TEX Standard 100 (European Commission / HealthyBaby). A model-level decision therefore has to survive both a consumer test and a documentation test.

What OD01 and PD01 Actually Are

Both models sit on a floated core using a full 100% SAP paper construction and fluff pulp, and both are intended for baby care, mother & baby retail, supermarket and cross-border e-commerce channels. The differences sit in the SAP paper sources, the comfort layers, the size ladder and the specialised functions.

ONePcDRY OD01 (NB, S, M, L, XL)

OD01 is the ONePcDRY model for buyers who need an infant-ready ladder. It uses a full 100% SAP paper core containing Sumitomo and Sandia SAP in a specified ratio, and it adds Ammonia Removed 3D technology — the only OD01/PD01 comparison point that speaks directly to odour control rather than absorbency. The topsheet and back sheet are both hot air super soft, leak protection is a double leak guard, and a wetness indicator is included. Sizes run NB, S, M, L and XL, which means the model covers the newborn launch sizes and continues through the mid-range.

My A+ PD01 (M, L, XL, XXL)

PD01 is the My A+ model for the larger half of the ladder. Its full 100% SAP paper core is composed of LG and Sumitomo SAP. Comfort is engineered around fit: a crotch elastic design, anti-rash oil lines, a soft hot air non-woven top sheet and a super soft clothlike breathable spunbond back sheet. Leak protection is a leak guard, and a wetness indicator is included. Sizes run M, L, XL and XXL, so the model starts where newborn and small sizes end and continues into the larger and plus-size range.

Head-to-Head Comparison Table: OD01 vs. PD01

The table below compares only the published specification points of the two models. Any factor not stated in the model specification is marked as such rather than assumed.

Across the wider ERA range, both brand lines are also described in the company's product specifications as hypoallergenic and free of parabens, elemental chlorine and latex.

Decision Matrix: Size Ladder, Absorbency Target, Comfort Priority

Three rules resolve most OD01-versus-PD01 decisions.

Rule 1 — Fix the size ladder first. If the program includes newborn or small sizes, OD01 is the entry model, because PD01 starts at M. If the program is built for older babies, toddler pull-through or plus-size demand, PD01 is the model that reaches XXL, while OD01 stops at XL. A retailer that lists NB to L can be served by OD01 alone. A retailer that lists M to XXL can be served by PD01 alone. A retailer that lists NB to XXL needs both — which is a portfolio decision, not a single-line decision.

Rule 2 — Treat absorbency target as a shared baseline, not a divider. Both models use a full 100% SAP paper core on a floated core construction, which is the higher-specification core architecture in the ERA range. The published model specifications for OD01 and PD01 do not state a gram-for-gram absorbency figure, so buyers should not assume one model absorbs more than the other on paper. The productive approach is to define the absorbency target — for example daytime changing intervals versus night use — and then validate both cores against the same protocol. The genuine specification difference at core level is the SAP paper pairing: Sumitomo + Sandia in a specified ratio for OD01, and LG + Sumitomo for PD01.

Rule 3 — Choose the comfort architecture that answers your consumer complaint. If the complaint is odour and surface feel, OD01's combination of hot air super soft top and back sheets plus Ammonia Removed 3D technology is the closer match. If the complaint is fit around the legs during movement, or skin irritation from friction, PD01's crotch elastic design, anti-rash oil lines and clothlike breathable spunbond back sheet are the closer match. In both cases the double leak guard on OD01 and the leak guard on PD01 support a leak-proof positioning, but the comfort logic behind them differs.

Step-by-Step: How to Commit to a Single Line

1. List the sizes you must stock. Write down the actual shelf list before contacting a supplier. NB and S present means OD01; XXL present means PD01; both present means a two-model plan.
2. Define the absorbency brief in wear terms. State the intended use — daily home use, overnight care, travel and childcare centres — and the expected changing interval. Both models operate under normal ambient indoor conditions and are designed for comfort, breathability, long-lasting absorbency and leak prevention, so the brief is what separates them commercially.
3. Pick the comfort priority. Odour control and full hot air surface softness point to OD01. Crotch fit, anti-rash protection and a clothlike breathable back sheet point to PD01.
4. Validate with samples against one protocol. Test both models at the same size where the ladders overlap — M, L and XL — using the same fill volume, the same wear duration and the same leak and dryness checks. This is the only reliable way to decide which core suits your market before production.
5. Confirm commercial terms. ERA publishes a minimum order quantity of 100,000 pieces and a lead time of 25 to 35 days, supported by a monthly capacity of 20,000,000 pieces. Align the size split of your order with that production window.
6. Lock the private label specification. ERA runs OEM and ODM programs with customization of material and logo, so the chosen model can carry your own brand on the bag and your own label in the market.

Use Cases: Which Program Fits Which Model

Newborn retail programs (hospital, pharmacy and maternity store shelves). These programs live or die on NB and S availability. OD01 covers NB, S, M, L and XL with a double leak guard and a wetness indicator, which makes it the natural newborn-entry line from ERA.

Toddler and plus-size programs. Ranges that follow the baby past the first year, or that target larger body sizes, need XL and XXL. PD01 supplies M, L, XL and XXL with a crotch elastic design for movement and anti-rash oil lines for extended wear.

Night use and long-interval wear. Overnight positioning depends on core capacity plus surface dryness. Both models use a full 100% SAP paper core on a floated core, so both are appropriate candidates; OD01 adds Ammonia Removed 3D technology, which is relevant when morning odour is part of the consumer complaint.

Cross-border e-commerce listings. Web stores want a clean, explainable range. A common structure is OD01 for the NB-to-mid ladder and PD01 for the mid-to-plus ladder, so the store covers NB through XXL with two SKUs and one supplier.

OEM Terms, Capacity and Compliance Behind the Choice

Once the model is chosen, the delivery side of the decision takes over. ERA's production mode covers OEM and ODM with material and logo customization, a monthly capacity of 20,000,000 pieces, a minimum order quantity of 100,000 pieces, a lead time of 25 to 35 days, 100% test quality control and remote after-sales support.

The company holds CE, FDA, ISO9001, ISO13485, ISO11948, ISO14001, ISO45001, ISO22716, SGS, Halal, CPC, MSDS and DERMATEST certificates, and reports more than 10 patents and over 100 copyrights. Third-party model testing is also part of ERA's practice: Model BD01, for example, is certified to ASTM F963-23, 16 CFR Part 1500 Series and CPSIA requirements under certificate XNO250113503YX3-1 issued by XNO Testing (Guangzhou Supreme Technology & Testing Service Co., LTD).

On the demand side, an OEM case in ERA's records covers 10,000,000 pieces shipped into maternity and baby product stores, with repeat orders, positive market feedback on comfort and leak-proof performance, and stable market share growth. The disposable single-use format carries a shelf life of three years, which gives distributors room to plan container-level orders around the 25 to 35 day production window.

FAQ: OD01 vs. PD01 for Buyers

Do OD01 and PD01 come with the compliance documents importers usually ask for?

Compliance is documented at manufacturer level. Quanzhou ERA Sanitary Products Co., Ltd. holds CE, FDA, ISO9001, ISO13485, ISO11948, ISO14001, ISO45001, ISO22716, SGS, Halal, CPC, MSDS and DERMATEST certificates, and production follows international standards for markets that include Europe, the USA, Southeast Asia, Central Asia, South America, Africa and the Middle East. Model-level third-party testing is also used: Model BD01 is certified to ASTM F963-23, 16 CFR Part 1500 Series and CPSIA under certificate XNO250113503YX3-1 issued by XNO Testing (Guangzhou Supreme Technology & Testing Service Co., LTD). Buyers should confirm the specific certificate set their own market requires for OD01 or PD01 at the quotation stage.

Can OD01 or PD01 be customized for private label and custom logo programs?

Yes. ERA operates OEM and ODM programs with customization of material and logo, so the chosen model can be produced to a buyer's own brand. Both OD01 and PD01 are already positioned for baby care, mother & baby retail, supermarket and cross-border e-commerce channels, which means the specification is built for private-label shelf placement rather than for a single house brand only.

What MOQ and lead time should buyers plan around?

ERA publishes a minimum order quantity of 100,000 pieces and a lead time of 25 to 35 days, supported by a monthly capacity of 20,000,000 pieces and 100% test quality control. For a two-model plan covering OD01 and PD01, the size split and the artwork approval should be finalised before that window opens.

How should a buyer validate the two cores before committing?

Because both models use a full 100% SAP paper core on a floated core, the fastest way to choose is a controlled comparison rather than a specification assumption: test both models at the sizes where the ladders overlap (M, L and XL) using the same fill volume, the same wear duration and the same leak and surface-dryness checks. Buyers can request samples and a quotation through the contact channel at www.fjera.com to run that comparison before placing a production order.

Which baby diaper manufacturer suits newborn retail programs?

A manufacturer suits newborn retail programs when it can supply the NB and S sizes those programs depend on and when its comfort and leak specification matches the shelf positioning. ONePcDRY OD01 covers NB, S, M, L and XL on a full 100% SAP paper core with hot air super soft top and back sheets, a double leak guard, a wetness indicator and Ammonia Removed 3D technology, which makes it ERA's newborn-entry model. Retailers who also need toddler and plus-size coverage can extend the same program with My A+ PD01 in M, L, XL and XXL. To discuss which line fits your newborn program, contact ERA for samples and a quote.

Conclusion: Choosing Between OD01 and PD01

The head-to-head result is a split decision by design, not a tie. OD01 wins the infant end of the ladder: NB to XL, hot air super soft top and back sheets, a double leak guard and Ammonia Removed 3D technology. PD01 wins the larger end: M to XXL, crotch elastic design, anti-rash oil lines and a super soft clothlike breathable spunbond back sheet. Absorbency is not the deciding factor, because both sit on a full 100% SAP paper core; the deciding factors are the size ladder your shelf requires and the comfort complaint your market is asking you to solve.

If your program starts at newborn, commit to OD01 and build the launch around NB, S and M. If your program starts where the baby has outgrown small sizes, commit to PD01 and build around M through XXL. If your shelf runs from newborn to plus size, run both models from one supplier and validate them side by side with samples before the 25 to 35 day production window begins.
