Storage Temperature Control: PVC is heat-sensitive. Bulk inventory must be stored below 30°C (86°F), away from direct sunlight, radiators, or steam pipes to prevent premature shrinkage or deformation.
Heat Shrink Parameters: For flawless application, calibrate heat tunnel, steam tunnel, or industrial heat gun between 120°C to 150°C (248°F to 302°F). Excessive heat can cause melting or splitting, while insufficient heat leads to uneven shrinkage.
Dimensional Tolerance: Capsule inner diameter should be 1-2mm larger than the maximum outer diameter of your bottle's primary cap. Share complete bottle and cap technical drawings for perfect dimensional specification.
Air Venting Configuration: For dry-heat shrink tunnels, opt for top discs with ventilation holes to allow trapped air to escape, preventing air bubbles on the cap surface.
