LONSUN
This carrier tissue is engineered specifically as the wrapping layer for diaper absorbent cores. Made from 100% virgin USA pulp, it serves as the structural envelope that holds fluff pulp and superabsorbent polymer (SAP) together within the core. The tissue keeps SAP particles contained, preventing them from migrating to the topsheet and contacting the wearer's skin—a common cause of irritation and discomfort in diapers with poorly wrapped cores.
In a typical absorbent core, SAP granules are mixed with fluff pulp. Without adequate wrapping, these fine particles can escape during manufacturing, transport, and use. Once outside the core, wet SAP forms gel-like beads against the skin, creating friction and irritation. The carrier tissue acts as a physical barrier that contains the SAP while still allowing liquid to pass through at high speed.
Beyond containment, this tissue also provides the wet strength needed to survive saturation. A core wrap that disintegrates when wet leads to core breakup and leakage. Our tissue maintains its structural integrity even when fully saturated, keeping the absorbent core intact throughout use.

Designed for jumbo roll converting on high-speed diaper lines, this carrier tissue is used in the absorbent core of:
Baby diapers
Adult incontinence products
Sanitary napkins and panty liners
High wet strength — maintains integrity even when saturated, preventing core rupture
Excellent porosity — allows rapid liquid strike-through without becoming a barrier
Anti-caking — keeps SAP distributed evenly throughout the core, avoiding clumping and ensuring consistent absorption
Skin-safe — contains SAP particles, keeping them away from direct skin contact
Eco-friendly production — made from 100% virgin wood pulp with responsible sourcing
This tissue is produced on modern papermaking equipment with in-line quality control systems. Basis weight, tensile strength, and absorbency are monitored continuously to ensure batch-to-batch consistency. Each jumbo roll is wound to precise specifications for smooth unwinding on diaper converting lines.
Custom widths and roll diameters are available for specific production requirements. Standard packaging is shrink-wrapped PE film on pallets, suitable for container shipment.
