When buyers begin to evaluate detergent sheets, the search usually starts with a product category but quickly turns into a supplier question. This article explains the detergent sheet format, how a multifunctional sheet is designed to work, and what a buyer should expect from a real manufacturer. Zhejiang Kelee Technology Co., Ltd. is used along the way as a practical reference because it is a direct manufacturer of laundry detergent sheets and related solid-form cleaning products.

The Sourcing Problem Behind a Growing Category

Retail shelves and e-commerce listings often present detergent sheets as a simple consumer switch from liquid detergent. For B2B buyers, however, the decision requires more than liking the product idea. A buyer needs to check whether the supplier owns the formulation, the production line, the quality system and the export experience required to deliver consistent private-label or OEM product.

Public descriptions of detergent sheets often focus on convenience, but they rarely show the factory evidence behind the product. That evidence includes established manufacturing facilities, in-house research and development, quality certifications, third-party testing and concrete product specifications. This guide treats those points as the core of any detergent sheet sourcing decision.

What Are Detergent Sheets?

Detergent sheets are flat, pre-measured formats of solid laundry detergent. Instead of pouring liquid or scooping powder, the user places a sheet into the wash load. The sheet releases cleaning ingredients during the cycle and is designed to dissolve without leaving a heavy plastic bottle behind.

The concept works well for compact cleaning because it removes unnecessary water content from the product. A concentrated sheet takes less storage space and can be produced with less packaging waste than a bottle of liquid detergent. Many detergent sheets also contain enzymes, which help break down common stains such as sweat, body grease and everyday household dirt.

Two terms appear frequently in this category. Enzymatic stain removal laundry sheets are sheets formulated with enzymes to improve cleaning on biological stains. 3 in 1 Multi-functional Laundry Detergent Sheets are sheets that combine cleaning power with additional benefits such as anti-color-transfer protection and fabric softening.

Industry Background: Why the Format Is Growing

Market research provides one indication of the category’s commercial momentum. A 2025 market estimate pegged the global laundry detergent sheets market at approximately USD 1.26 billion, with a projected increase to roughly USD 2.82 billion by 2034. That projection suggests continued interest from retailers, travel suppliers and home-care brands.

The same solid-form thinking appears in related cleaning formats, including dishwasher sheets, detergent tablets, hand soaps and other compact daily chemical products. These formats address different cleaning tasks and compliance requirements, but they share a common goal: reduce water weight, reduce plastic waste and make dosage easier for the end user.

For hotels, business travelers and households that want a compact laundry option, detergent sheets offer practical advantages. They are lighter than liquid detergent, flat enough for small packages and less likely to leak during transport or storage.

Behind the Product: Zhejiang Kelee Technology Co., Ltd.

One of the manufacturers active in this sector is Zhejiang Kelee Technology Co., Ltd., a company established in 1999. Its facility is located in Yiwu, Zhejiang Province, China, a region known for global trade in consumer goods. The company describes itself as a high-tech manufacturer of solid-form cleaning and washing products, with a focus on compact, environmentally conscious alternatives to traditional liquid detergents.

Kelee’s manufacturing base covers approximately 16,000 square meters. The company employs roughly 150 people and reports production output of about 30,000,000 units per year. Its R&D team consists of eight engineers, which gives the company an in-house capability to review formulas, support product customization and manage quality parameters before mass production.

Export business accounts for approximately 70% of the company’s total sales. Major markets include the EU and the USA, regions where buyers usually require clear product documentation and factory compliance evidence. Kelee also operates with ISO 9001 quality management, ISO 14001 environmental management and ISO 45001 occupational health and safety management system certifications. Key products complete SGS third-party safety and performance testing.

The company’s product range covers laundry care, household cleaning, personal hygiene and travel-friendly cleaning goods. In addition to laundry detergent sheets, it develops formats such as floor cleaning sheets, dish-washing sheets, hand-washing flower-shaped soap sheets and pet cleaning series. This breadth matters to buyers because it shows experience in solid detergent formulation beyond a single SKU.

Kelee also provides OEM, ODM and private-label services for national and international brands. Small-batch customized orders can be reviewed alongside large production runs, giving customer teams flexibility during product testing and market launch.

Product Example: The 3-in-1 Multi-Functional Detergent Sheet

A representative product in Kelee’s laundry range is the 3 in 1 Super Multi-Purpose Laundry Detergent Sheet, model KL-R2015. This product is useful for understanding what a multifunctional laundry sheet can contain.

The KL-R2015 is categorized as a daily chemical product and is designed for household, travel and business trip scenarios. It combines cleaning, anti-color-transfer protection and a softening effect in one sheet. The anti-color-transfer function is especially relevant for buyers who want a simple answer to mixed-color washing: the sheet absorbs free-floating dye during the wash, reducing the risk of colour bleeding between light and dark clothes.

Key specifications for the KL-R2015 include a white sheet with an ocean scent, 1% fragrance plus 1% microcapsule, softener and enzyme content. Each sheet measures 11 × 12.5 cm and weighs 3 ± 0.5 g. The standard package format is 30 sheets per box. The formula is positioned as gentle on fabrics, including delicate materials and children’s clothing, and is intended to reduce fabric static after washing.

For buyers, this type of specification sheet is important because it shows dosage, fragrance loading and functional additives in a measurable way. It also shows that a detergent sheet does not have to be a single-purpose product. It can be designed as a system that replaces several separate laundry additives.

Step by Step: How to Use a Laundry Detergent Sheet Correctly

Correct usage prevents most of the problems consumers report with detergent sheets. The method is not the same as dosing liquid detergent into a drawer.

1. Place the laundry sheet directly into the empty washing machine drum.
2. Do not put the sheet into the detergent drawer. The sheet is designed to dissolve when it meets water in the drum.
3. Add clothes on top of the sheet.
4. Use one sheet for a normal-size load of about 4 to 5 kg of dry clothes.
5. Use two sheets for a large load, heavily soiled clothes, thick bedding or towels.
6. For a small half-load, tear one sheet in half.
7. Start the wash cycle and let the sheet dissolve during washing.

If a consumer sees undissolved fragments, the first cause is usually usage method rather than product quality. The most common causes are placing the sheet in the detergent drawer or overloading the drum. Following the dosage and placement instructions avoids most residue issues.

Use Cases: Household, Travel, Hotel and Brand Programs

The practical value of detergent sheets depends on the scenario. The following use cases show why the format suits more than one type of buyer.

Household Laundry

In a normal household washing machine, a detergent sheet replaces a measured capful of liquid detergent. A 3-in-1 version can also remove the need for a separate fabric softener or color-catcher during mixed-color washes. This simplifies laundry routines and helps family users avoid overdosing.

Delicate Fabrics and Children’s Clothing

Some laundry sheet formulas are designed to be mild. The KL-R2015 specification, for example, highlights a skin-friendly formula and gentle performance on delicate fabrics and children’s clothing. Manufacturers should always confirm individual formulas before a buyer makes label claims, but this product direction supports demand for milder daily cleaning options.

Travel and Business Trips

Light and thin sheets are convenient for travel. They do not create liquid leakage risk in a suitcase and they allow portion-controlled washing in hotel laundries or shared machines. This helps explain why hotel travel disposable laundry sheets are now a common private-label format.

OEM and Custom Projects

For brands, the detergent sheet category allows several entry paths. A buyer can choose an existing base formulation, adapt a scent or package, or request a private-label program. Custom scent OEM laundry detergent sheets are a common brief because fragrance is one of the easiest brand points to differentiate. Kelee’s OEM/ODM service structure means such projects can be discussed with the in-house production and R&D team.

Detergent Sheets vs Traditional Liquid Detergent

The most common comparison in this category is detergent sheets versus conventional liquid detergent. The table below outlines the structural differences based on product design and typical usage patterns.

This comparison is a general structural overview. Different liquid detergents and different sheet formulas vary in performance. Buyers should always validate with physical samples and reference a spec sheet that states the actual formulation and dosage.

Step-by-Step Sourcing: Questions to Ask a Detergent Sheet Manufacturer

Buyers researching detergent sheets should treat factory verification as a process, not as a single sales conversation. The following questions form a practical checklist for the research stage.

1. Is the supplier a manufacturer or a trading company? A direct manufacturer should be able to show its production site, clean workshop and production lines. Kelee, for instance, is a direct high-tech manufacturer with a 16,000-square-meter facility and 100,000-class dust-free workshop.
2. Can the factory be visited or viewed remotely? Virtual factory tours and on-site visits help buyers verify that the product is made in-house. Kelee offers virtual tour channels that show the production process to overseas clients.
3. Which certifications and third-party tests are available? Quality management, environmental systems and product safety testing are standard reference points. ISO 9001, ISO 14001, ISO 45001 and SGS testing are all visible in Kelee’s compliance profile.
4. What does the product spec sheet actually state? Sheet size, weight per sheet, package count, fragrance, enzyme content and recommended dosage are essential data. A spec sheet should explain the product in measurable terms, not only with benefit phrases.
5. What OEM/ODM services are available? Ask whether the supplier can handle private-label packaging, custom scent projects, different sheet weights and different order quantities. Kelee’s range of OEM, ODM and private-label services is one signal of manufacturing depth.
6. What is the export experience? Export markets affect documentation, packaging language and compliance expectations. Kelee exports about 70% of its production and serves the EU and the USA, two markets with rigorous buyer requirements.
7. How can the buyer start? Most serious manufacturers respond well to a clear inquiry that includes target market, product type, estimated quantity and desired packaging. A first sampling round will normally confirm whether the supplier’s actual product matches the documented specification.
