Materials for Sanitary Napkin Production

Choosing the right sanitary napkin materials for your feminine care products is essential. We know the challenges and expectations that come with the manufacturing of these products. Demands are diverse and the products must meet consumer expectations. Hot melt adhesives are designed to meet the production challenges for feminine hygiene products. They withstand the absorbency demands and support positioning needs for the products. Henkel’s TECHNOMELT® line of adhesives offers a complete line of material solutions for positing, core, and construction applications.

Positioning Adhesives

Henkel developed adhesives specifically for positioning that keep sanitary pads where they are supposed to stay. Our TECHNOMELT® adhesives are used on sanitary napkin wings (side flaps) and the backsheet. These advanced sanitary napkin materials for positioning are specially designed for feminine care products to support both comfort and security to the consumer. TECHNOMELT® products provide high tack and good breathability to assure a secure fit for:

  • Wing application
  • Release paper application

Core Adhesives

Critical to construction of the sanitary napkins is a stable and absorptive core. This keeps the integrity of the product and allows it to stay securely in place. Henkel’s TECHNOMELT® core adhesives are used to stabilize the napkin core. They provide excellent wet-strength, improved fluid handling and guaranteed discretion. Our sanitary napkin materials assure good wear for an active lifestyle for:

  • Core efficiency
  • Core integrity

Construction Adhesives

The various layers within a sanitary napkin’s construction require maintaining position and no bunching within the layers. Henkel’s TECHNOMELT® sanitary napkin construction adhesives are applied in a very efficient and sustainable way. Our menstrual hygiene materials provide a good adhesion ratio and reduce production flaws caused by material movement. Our adhesives are designed for:

  • Top and backsheet construction
  • Top and bottom tissue
  • Acquisition distribution Layer
  • Air Laid/SAP Paper

Automation for Sanitary Napkin Production

The last several years have brought many changes to personal hygiene manufacturing. A number of these advances include increased automation on the production line and Industry 4.0 technology. Henkel is at the forefront of automation in personal hygiene applications with Easyflow®.

Keeping hot melt adhesive production lines running at high speeds, the challenge is maintaining a steady flow of adhesive to the production lines without increasing manpower or overfilling hot melt tanks. Henkel offers customers Easyflow® to solve their production challenges. Built around an innovative hot melt adhesive formulation, Easyflow® sets a new standard in process performance and efficiency. It offers:

  • Melt-on-demand capabilities derived from patented product form
  • Closed system integration to eliminate foreign materials in hot melt tanks
  • Auto feeding system to keep production moving

Adhesive Troubleshooting Sanitary Napkin Production

For over forty years, Henkel has been developing innovative adhesive solutions and therefore, has collected an extensive list of troubleshooting tips for sanitary napkin production. From preventing overspray and bleed through to hot melt safety, our adhesive troubleshooting tips help prevent unnecessary downtime and keeps production lines running smoothly.

Spray Adhesives

There are several factors that can affect spray adhesive technology, such as heat, time, and oxidation. All of these can lead to other issues along the production line and lead to downtimes. To avoid delays and quality control issues such as overspray and poor coverage, Henkel has developed a list of spray adhesive troubleshooting tips to improve production efficiency and reduce unnecessary downtimes. Our proven methodology helps to establish baseline settings and then further fine-tune each application to reach optimal performance.

Slot Coating Adhesives

Slot coating adhesive applications for feminine care products require direct contact between the hot melt applicator nozzle and the substrate. To achieve maximum production efficiency, understanding the slot coating process is important. Some common challenges are position of the applicator, nozzle build-up or damage, poor coverage, and bleed-through. Often these issues are related to incorrect process settings, poor equipment maintenance, substrate changes, or some combination of these variables.

Char

Hot melt adhesives are designed to cure quickly and are often used in fast paced packaging lines where efficiency and speed are important factors. However, heat, contaminants and oxidation can cause char which can clog hoses, filters, and nozzles. Preventing char is vital to avoid costly delays and repairs, especially because once char is in the system, it can be difficult to remove and can damage hot melt adhesive equipment.

Set Back Mode

Hot melt adhesive degradation is another factor that can lead to char. However, this can be avoided by implementing a tank setback mode. This will reduce wait times due to reheating or cooling the hot melt adhesive and keeps the material from darkening or char from forming due to being heated for too long.

Hot Melt Tank Refilling

Overfilling or underfilling hot melt tanks can cause of wide variety of issues which can cause delays. For this reason, establishing a regular tank filling routine will help prevent char from forming, as well as keeps the temperature in the tank consistent. We have developed a list of best practices that addresses a range of issues surrounding hot melt tank refilling.

Hot Melt Safety

To avoid workplace accidents, proper protections should be in place to prevent injuries and maintenance of hot melt adhesive equipment should carried out according to the equipment manufacturer specifications. By following our list of safety best practices, you can protect hot melt equipment operators against injury and reduce unexpected delays during production assemblies.
