Product Overview

50gsm SCK Release Paper is a white paper liner combining supercalendered kraft, PVA barrier treatment and a silicone release surface. For labels or hygiene adhesive materials, the backing specification and release requirement should be considered separately. Buyers can compare this weight with their approved web through slitting, winding and removal, using an identified adhesive construction. HENGMU can review the proposed reel dimensions and contact-face arrangement for the sample and subsequent quotation.

A PVA barrier forms part of the SCK layer structure.
The 50gsm backing has defined caliper and tear references.
White reel supply can follow a specified slitting format.
A separate release method identifies the adhesive-interface requirement.

Applications

Evaluate 50gsm SCK for labels and hygiene materials at the intended slit width. Inspect edge damage and unwind starts; test stored samples where release after ageing matters.
Customization

Specify slit tolerances, winding direction and reel capacity. Include adhesive, release method and conditioning requirements; request printing or face identification separately from the basic paper specification.
Selection Guide

Compare 50gsm with 40gsm using consistent release tests. Inspect slit edges and unwind starts, then evaluate removal after the conditioning period agreed for the finished product.
Quality & Documents

Obtain the 50gsm SCK specification and agree edge and release inspection criteria. Keep fresh and conditioned results tied to sample identity and the quoted coating arrangement.
Packaging & Delivery

Minimum order quantity: 1 metric ton. Dispatch within one month. Match wrapping and pallet dimensions to the approved roll build and receiving-equipment limits.
Technical Support

Ask for a 50gsm SCK trial arrangement. Describe edge or unwind issues; provide adhesive, ageing conditions, release method, slit dimensions, reel limits, quantity and destination.

FAQs

Can I compare an SCK peel value with one from another supplier?

Only after aligning the adhesive or reference tape, conditioning, peel geometry, speed and units. An isolated number cannot establish equivalent release behaviour.
What changes if I move from 40gsm to 50gsm SCK?

The specified caliper rises from 40 ± 5μm to 50 ± 5μm; the backing-strength limits also differ. Confirm tooling and roll build, then test the adhesive construction without assuming that release force changes with gsm.
50gsm SCK: How should I assess a move from my current liner?

Keep the existing material as a control and record actual differences in coating and dimensions. Trial the finished construction under consistent conditions before accepting the new grade.
50gsm SCK: Does the product name confirm the number of release faces?

The name may not specify the complete coating configuration. Obtain the material construction and mark each adhesive-facing surface in the inquiry and roll drawing.
