Products Introduction

Our period pads for bathing suits feature fast-absorbing technology and a leak-proof design. They effectively absorb liquids and lock in moisture, even in the water, ensuring all-day dryness.
Water-proof design: A special waterproof layer ensures no leaks during underwater activities.
Quick-drying: The sanitary napkin quickly returns to dryness even after exiting the water.

We are committed to environmental protection and use biodegradable materials such as 100% organic cotton and bamboo fiber to ensure our products are gentle on the skin and environmentally friendly.
Organic cotton and bamboo fiber: Made from natural materials, they meet OEKO-TEX® Standard 100 and GOTS certifications.
Biodegradable: They naturally degrade after use, reducing environmental pollution.

These sanitary napkins are designed to be discreet and fit comfortably under swimwear.
Ultra-thin design: Maintains comfort without causing discomfort.
Excellent breathability: Keeps skin dry and prevents moisture buildup.
Common Problems
Product Features and Benefits
Underwater-Proof Design: The back layer utilizes an ultra-thin hydrophobic film/microporous waterproof material to effectively prevent pool/seawater from seeping in.
Water-Locking Absorbent Layer: The middle layer utilizes a highly effective water-locking material + plant fiber composite structure to prevent menstrual blood from leaking out.
Ultra-Thin Fit: Precision heat pressing/ultrasonic lamination minimizes the thickness to minimize swelling in water.
Elastic Edges/Curved Fit: The edge design conforms to the body's curves, preventing displacement.
Quick Moisture-Washing Layer/Flow-Diverting Structure: The top layer quickly wicks away moisture, and the flow-diverting design reduces the sensation of wetness.
Chlorine-Resistant/Salt-Resistant Materials: Materials selected with swimming pool/seawater environments in mind ensure durability and stability.
Individual Waterproof Packaging + Wet Bag Design: The portable packaging is moisture-proof and can be stored in a wet bag after use.
Technology/Material/Machine Application
Hydrophobic/Microporous Membrane: Used for the backing layer's anti-seepage properties. Polyurethane, PTFE, or biodegradable hydrophobic membranes are recommended.
Polymer + Plant Fiber Composite Absorbent: Provides excellent absorbency and prevents uncontrolled expansion in water.
Hot Pressing/Ultrasonic Edge Sealing: Enhances edge strength and prevents interlayer delamination.
Die-Cutting/Laminating Equipment: Precision die-cutting and laminating each layer of material to ensure consistent dimensions and eliminate scraps.
Chlorine/Seawater Treatment: Adds chemical-resistant agents to the material or coating to improve durability.
FAQ
Q: Will this spacer expand in water?
A: The membrane + absorbent combination controls expansion. Slight expansion may occur only during extremely heavy flow or prolonged submersion in water.
Q: Can it be used in place of a menstrual cup in water?
A: This product is a supplemental spacer suitable for light to moderate flow. For heavy flow or nighttime use, it is recommended to use with a tampon/cup.
Q: Will the chlorine in swimming pools damage the spacer?
A: We use chlorine-resistant materials and conduct chlorine resistance testing, but we recommend rinsing with clean water after use to extend its life.
Q: What should I do if the spacer shifts?
A: We recommend testing it in a dry environment before wearing it. The edges are designed with elastic to help with the fit. If it still shifts, you can adjust the position slightly or add a fixator.
Q: How should I dispose of/dispose of it after use?
A: After use, rinse with clean water (if possible), then wrap and dispose according to the packaging instructions. If it is made of biodegradable material, it can be disposed of according to composting conditions.
