As global food safety regulations become increasingly stringent, the flexible packaging industry is undergoing a fundamental shift. Traditional solvent-based lamination processes — long the industry standard — are being replaced by cleaner, safer solvent-free alternatives. At Heshan Xinglong, we made this transition years ago, and the results speak for themselves.
What Is Solvent-Free Lamination?
Solvent-free lamination is a bonding process that joins multiple film layers together using adhesives that contain no organic solvents. Unlike conventional lamination, there is no drying oven needed to evaporate solvents, which means:
- Zero solvent residue in the finished packaging material
- No VOC emissions released during production
- Lower energy consumption (no oven heating required)
- Faster curing times for higher production throughput
Why It Matters for Food Packaging
For food-contact packaging, even trace amounts of solvent residue can interact with food contents, affecting taste, smell, and — more critically — consumer safety. Solvent-free lamination eliminates this risk entirely. This is why our food packaging line operates exclusively on solvent-free technology, fully compliant with ISO 22000 food safety management standards.
Major international retailers and brands are now requiring solvent-free certification as a baseline requirement for their packaging suppliers. By adopting this technology early, we help our B2B partners stay ahead of regulatory curves.
Our "Tech Downdimensioning" Advantage
At Xinglong, our solvent-free capabilities were born from over a decade of manufacturing agrochemical packaging — where the consequences of adhesive failure or chemical migration are catastrophic. We applied the same zero-tolerance engineering philosophy to consumer food packaging.
This "Tech Downdimensioning" approach means our food-grade pouches are engineered to standards far exceeding typical industry requirements. When you partner with us, you're getting agrochemical-grade reliability in a food-safe package.
Ready to Switch to Solvent-Free?
If your current packaging supplier still uses solvent-based lamination, it may be time to upgrade. Contact our team for a free consultation and sample pouches manufactured with our solvent-free process.
