Perfumes and Lotions

Perfume and lotions are sometimes applied to sanitary napkins/towels. The perfume can be acknowledged as a hot-melt-like liquid, in which case it may be applied with slot coat applicator. In contrast, the substance's formula may be oil based.  In this case, a cold glue dispensing system would be best suited for the job. Spray application is not the most cost-effective option, as most of the perfume is dispensed into the air. To avoid wasting product, a precise bead application is better utilized. Because perfumes and lotions are highly corrosive, having the proper equipment fitted with ceramic seats and/or nylon and steel module bodies will most likely make a huge difference in regards to maintenance.

Sealing a Poly Pouch 

To seal the last fold of a poly pouch bag, a slot coat is often used.  As an alternative option, the bead applicator may be installed. Because poly pouch bags are highly sensitive and can be deformed easily, a PSA generally known by the name of 'Low Temperature Adhesive' is most commonly used. This adhesive is known to have a low softening point. In some cases, 'Construction Adhesive' can be used, but must be applied at lower temperatures.

Poly Pouch Easy Wrap

In a Poly Pouch Easy Wrap Application, adhesive is used on the poly pouch cover of the sanitary tower so that when it is removed, the release paper is also uncovered. This is achieved by bonding the outer area of the release paper to the inner area of the poly pouch bag. The high speed intermittent slot coat applicator is typically used for this application to provide extremely clean cut-off necessary to ensure good respiration.  A PSA with a low softening point, generally known as 'Low Temperature Adhesive,'  is the most common typical adhesive used during this application. The Poly Pouch bag is highly sensitive and can be deformed easily. In some cases, 'Construction Adhesive' can be used, but must be applied at lower temperatures.

Sanitary Napkin Wing Applications

'Positioning' Adhesive Application is used on a feminine napkin's two side flaps, also known as the 'wings', so that an end-user may stick the final product around the outer side of their underwear. The adhesive is most typically applied to a silicone release liner or paper that covers the wings, so that it may be later transferred back to the wings material. The high speed intermittent slot coat applicator is typically used for this application to provide extremely clean cut-off necessary to ensure good respiration. The most common adhesive used for this application is a PSA known as 'Positioning Adhesive' whose main feature is high tack.

Release Paper Applications

Adhesive application is used on Release Paper of a sanitary towel's back sheet, so that an end-user may stick the final product to the inner side of their underwear. Adhesive is typically applied to a silicone release liner or paper that covers the sanitary towel, so it can be later transferred to the back-sheet material. The high speed intermittent slot coat applicator is typically used for this application to provide extremely clean cut-off necessary to ensure good respiration.  The most common adhesive used for this application is a PSA known as "Positioning Adhesive" whose main feature is high "tack."

Top Tissue and Bottom Tissue

The top tissue and bottom tissue of a feminine product are layers of paper that are placed over and/or under the absorbent pad to help keep the SAP (Super Absorbent) in its place and reduce waste of this material throughout the sanitary napkin/towel manufacturing process. These layers are most commonly glued with a spray application to reduce adhesive consumption. The most common adhesive used for this application is a PSA called "Construction Adhesive," generally known to have a good adhesion ratio.

Acquisition Distribution Layer

The Acquisition Distribution Layer of a feminine product, also known as  ADL, AQL, is a patch of material used on top of the absorbent pad as a reservoir to provide time for the SAP (Super Absorbent) to work. This patch is normally bonded to inner area of the Top Sheet. Because breathability is a necessity, non-contact spray is the preferred method of application. The most common adhesive used for this application is a PSA called "Construction Adhesive," generally known to have a good adhesion ratio.

Air Laid or SAP Paper

In Air Laid or SAP Paper Adhesive Application, ultra-thin sanitary towels are manufactured with an airlaid layer of SAP instead of the typical fluff & SAP core. This application requires wrapping the SAP to the airlaid material, as well as fixing the SAP onto the Airlaid. This application is normally done with spray. The most common adhesive used for this application is a PSA called "Construction Adhesive," generally known to have a good adhesion ratio.

Top Sheet Construction

In feminine hygiene product manufacturing, Top Sheet Construction, also known as NW Construction, or Nonwoven Construction, the top sheet is the inner face of the sanitary towel that touches an end-user's skin. During manufacturing, adhesive is applied along the full length of the sanitary towel in order to bond it to the lower layers of the sanitary towel. Because liquids must fall through, breathable adhesive applications, such as a non-contact spray, are usually preferred.  The most common adhesive used for this application is a PSA called "Construction Adhesive," generally known to have a good adhesion ratio.

Back Sheet Construction

In back sheet constuction for diapers and incontinence applications, also known as PE Construction or Outer Cover Construction, the back sheet is the outer layer of the diaper. It is made of film, normally PE (polyethilene), or a textile laminate, designed to contain the liquids.  The adhesive is applied along the diaper's full outer layer to bond it to the other upper layers. This leaves unglued areas for the leg elastics. The typical adhesive used for this application is a PSA generally known as "Construction Adhesive" whose main property is a good adhesion ratio.
