Stick packs and sachets for pharma: flexible packaging built for protection, dosage accuracy and recyclability
Pharmaceutical products come in many forms: powders, granules, liquids, suspensions and effervescents. Each of these formats needs packaging that can guarantee product integrity from filling line to patient use. Gualapack's stick pack and sachet laminates for pharma are designed to meet this need, combining high-performance flexible packaging with pharmaceutical grade quality standards.
Stick pack and sachet laminates are engineered to protect the integrity of pharmaceutical powders, granules and liquids while ensuring convenience, safety and excellent shelf life. This makes them a relevant packaging format for single-dose and unit-dose pharmaceutical products, where accurate dosage and product stability are essential.
Gualapack product range is structured around four core areas:
product protection: high barrier against moisture, oxygen and light, which helps preserve product stability over time
patient convenience: a single-serve format designed for accurate dosage, with easy opening features
efficiency and versatility: laminates optimized for high-speed filling lines and compatible with multiple product types
sustainability options: mono-material solutions, designed for recycling, available as part of the range
excellent barrier: protection against moisture, oxygen and light
mono-material PP: a recyclable-ready solution that supports sustainability strategies
high-seal performance: strong and reliable seals for product protection
outstanding print quality: high-definition printing up to 10 colors
optimized for high speed: engineered for excellent machinability and productivity on filling lines

Customers can choose from three main structure types depending on barrier, sustainability and cost requirements:
conventional laminates: PET (12 µm) print layer, ALU (7 µm) barrier layer, PE (40 µm) sealant layer
paperbased conventional laminate: paper (50 g/sqm) print layer, ALU (20 µm) barrier layer, PE (35 µm) sealant layer
mono-material PP: BOPP (30 µm) print layer, MetBOPP (16 µm) barrier layer, PP (40 µm) sealant layer
For customers looking for a recyclable-ready solution, the mono-material PP structure, part of the LamiNEXT recyclable range, is built from a defined layer sequence: high thermalsability BOPP for excellent print quality, inks, adhesive, high barrier MetBOPP for optimal product protection, adhesive, and high performance sealing PP for strong and reliable seals.
This structure is designed to deliver on four fronts at once: high barrier for product protection, sustainable packaging for lower environmental impact, mono-material PP designed for recyclability, and strong sealing that's reliable and leak-proof. It's worth noting that recyclability depends on local recycling streams and infrastructure.
