Our 21mm x 20mm Plastic-Free Shrink Sleeves give pharmaceutical vials a secure, sustainable, and professional finish. We design them with care to meet the strict needs of industries that require safety, accuracy, and compliance.
In addition, these sleeves are made of eco-friendly, plastic-free material. This means you get the same strength and reliability as traditional sleeves while also cutting environmental impact. The 21×20 size fits pharmaceutical vials neatly and creates a tamper-evident seal. As a result, products stay protected and end users gain confidence.
Moreover, these sleeves work well in many different settings. For example, you will find them in microbiology labs, test kit production, and pharmaceutical packaging lines. Beyond this, they also perform well on fuel and air test kits, where both security and clear identification matter most.
Overall, our 21×20 white Plastic-Free Shrink Sleeves bring together sustainability, practicality, and strong performance, giving your business a smarter and greener way to package pharmaceutical products.
