Structures of absorbent disposable underpads of MEDMIL LLC:
Absorbent disposable underpads, produced by our company, are rectangular multilayer products, the layers of which are bonded by a hot-glue method (by spraying hot melted glue with subsequent rolling through a system of hot stamping shafts).
The top of the underpad is covered with a nonwoven hydrophilic material that easily allows liquid to pass through. The inner (middle) layer – the absorbent underpad core – consists of layers of special tissue paper and fluff pulp, with possible special additives. The lower layer of the underpad – which protects against liquid leakage – consists of a PE film or other waterproof materials.
Depending on the purpose and brand of the product, we use different types of structures, different densities of materials and types of additives. The products differ in weight, size parameters, and specific density. The main variants of the structures of our underpads and the differences in their production technology are listed below:
Composition: 1. Coating layer: hydrophilic nonwoven material. 2. Absorbent layer: fluff pulp. 3. Supporting layer: sanitary-hygienic tissue paper, on which pulp is laid out. 4. The lower layer that protects against leakage: PE film.
Scheme of 4-layer products:
1. Coating layer: nonwoven material
2. Absorbent layer: fluff pulp
3. Supporting layer: sanitary tissue paper.
4. Protective layer: PE film
Composition: 1. Coating layer: hydrophilic nonwoven material. 2. Covering (distributing) layer of tissue paper. 3. Absorbent layer: fluff pulp. 4. Supporting layer: sanitary-hygienic tissue paper, on which pulp is laid out. 5. The lower layer that protects against leakage: PE film.
Scheme of 5-layer products:
1. Upper coating layer: nonwoven material
2. Covering (distributing) layer of sanitary tissue paper
3. Absorbent layer: fluff pulp
4. Supporting layer: sanitary tissue paper
5. Protective layer: PE film
Composition: 1. Coating layer – hydrophilic nonwoven material. 2. Covering layer of tissue paper. 3. Layer of powder (granules) of a super absorbing polymer (SAP). 4. Absorbent layer – fluff pulp. 5. Supporting layer: sanitary-hygienic tissue paper, on which pulp is laid out. 6. The lower layer that protects against leakage – PE film.
The structure of this underpad involves dense rolling – stamping of the canvas of the absorbent layers (2,3,4,5 layers) with the application of a permanent diamond-shaped pattern: the pattern grooves ensure rapid liquid distribution.
