AI Overview
Self-adhesive labels for small, curved functional food vials require specialized, flexible materials and aggressive adhesives to prevent flagging (peeling) and wrinkling. Optimal solutions include
Machine Directed Orientation (MDO) film or thin polyester (PET) with a "tight mandrel" adhesive designed for small diameters. These materials ensure the label conforms to the curve without lifting, while offering resistance to moisture and, if necessary, sterilization processes.Recommended Label Materials & Adhesives
- MDO Film (Machine Directed Orientation) BOPP: Best for, and specifically designed for,, curved or squeezable containers. It is thin and flexible, reducing the tension that causes label curling.
- Thin Polyester (PET) (50 Microns or 2-mil): Offers superior durability, tear resistance, and high conformity to tight curves, maintaining integrity under temperature fluctuations.
- Polypropylene (PP): Excellent for moisture, oil, and chemical resistance, suitable for functional food, refrigerated, or nutraceutical products.
- "Tight Mandrel" or "Tight Radius" Adhesive: High-performance, aggressive adhesives are necessary to hold labels on small, high-curvature surfaces.
Key Considerations for Vial Labeling
- Surface Tension & Material: When labeling small diameters, such as vials (e.g., 2ml–10ml), the label must have a "tight mandrel" adhesive to hold against the natural tendency of the material to straighten out.
- Environmental Factors: If the functional food requires storage in a freezer or refrigerator, use materials that are moisture-resistant and cold-temperature rated (e.g., cryogenic labels).
- Printing Method: For detailed nutritional information, thermal transfer or high-resolution digital printing is recommended to ensure readability on small surfaces.
- Compliance: Labels must meet regulatory requirements for, and ensure, food-contact safety if the label comes into contact with the product, though most vial labels are applied to the exterior.
