ASA sizing innovations
PapyraSeal® ASA Sizing
Advanced ASA-based sizing chemistry engineered for high-speed machines and demanding packaging applications.
What differentiates PapyraSeal
FDA
Food-contact compliant
PapyraSeal formulations maintain compliance for packaging and wrapper grades while securing moisture barriers.
C16/C18
Custom alkyl blends
Multiple ASA ratios available to tune hydrophobicity, emulsion stability, and runnability for each furnish profile.
On-site
Technical partnership
Trial support, dosing equipment, and particle size testing delivered directly at your machine center.
Engineered ASA emulsions
Formulations accelerate development, reduce sizing variability, and integrate with existing retention programs without disruptive chemistry overhauls.
Embedded technical specialists
Papyra teams install and calibrate equipment, monitor Cobb targets, and collaborate on continuous improvement roadmaps.
Responsive, domestic supply
U.S. manufacturing ensures stable delivery in totes or bulk volumes so programs scale without logistics friction.
Engineered for Superior Water Resistance
PapyraSeal® represents the next generation of ASA-based sizing chemistry, built to handle today's high-speed production targets and stringent packaging specifications. The formulations maintain excellent runnability, integrate with existing wet end systems, and are tuned to hit target Cobb values with lower chemical consumption.
Key Applications
- Food packaging and wrappers that must meet FDA compliance.
- Specialty boards requiring tight moisture management during converting.
- Fine papers demanding controlled hydrophobicity without surface defects.
- Recycled grades with variable furnish composition.
- High-speed environments where sizing consistency protects uptime.
Program building blocks
PapyraSeal deployments begin with granular process audits covering furnish variability, machine speed, and dosing infrastructure. Specialists engineer emulsions and surfactant packages specific to that data profile before trials begin.
