What Is a Shrink Band for Pre-Roll Tubes: Tamper Seal
What is a shrink band for pre-roll tubes wholesale? A heat-activated plastic sleeve placed over the cap. It contracts across the closure to provide visible tamper evidence. Ace quotes empty cones about 美元 $0.04–$0.06, MOQ applies. I will not print compliance claims on paper cones.

Statutory Tamper Evidence vs Child-Resistant Caps
I reviewed cannabis packaging regulations across multiple American and Canadian jurisdictions. State laws require retail cannabis containers to be both child-resistant and tamper-evident before customer checkout.
What is a shrink band for pre-roll tubes wholesale from a legal standpoint? A child-resistant cap prevents accidental opening by minors, while a shrink band proves nobody opened the container after filling. In my experience, a shrink band is the lowest-cost method to meet statutory tamper-proof requirements without buying expensive multi-part mechanical lock boxes.
| Closure Component | Primary Function | Application Method | Material Composition |
|---|---|---|---|
| Shrink Band | Visible tamper evidence | Heat gun or steam tunnel | Perforated PET-G or PVC film |
| Child-Resistant Cap | Prevents opening by minors | Squeeze-and-pull or push-and-turn | Molded polypropylene plastic |
| Primary Paper Cone | Holds ground flower | Vibration shaker table | Unbleached hemp or wood pulp |
Material Options: PET-G vs PVC Films
Shrink bands come primarily in two clear polymer plastics: PET-G (polyethylene terephthalate glycol) and PVC (polyvinyl chloride).
PET-G offers higher clarity, uniform shrinkage rates, and easier curbside recycling. PVC provides economical pricing and shrinks at slightly lower temperatures. I recommend PET-G for operations using steam heat tunnels because it avoids toxic off-gassing and wrinkles less during cooling.
Perforation Lines and T-Perf Tear Strips
Consumers struggle to remove non-perforated plastic bands without using knives or keys. Quality pre-roll bands incorporate vertical perforation lines or T-perforations with a pull tab.
What is a shrink band for pre-roll tubes wholesale on consumer satisfaction? A single pull along a clean perforation releases the cap instantly. Ace specifies laser-cut vertical perforations on custom-printed bands so dispensaries avoid customer complaints about stuck caps.

Procurement Checklist for Shrink Bands
I advise packaging supervisors to measure their exact tube cap dimensions before ordering custom printed sleeves.
| Measurement Metric | Measurement Method | Sourcing Impact |
|---|---|---|
| Layflat Width (LF) | Half the outer circumference in mm | Controls how easily the band slips over the cap |
| Cut Length | Total vertical height in mm | Ensures band covers the cap and tube shoulder |
| Shrink Ratio | Percentage of radial shrinkage (typically 50–70%) | Dictates tightness of final fit without splitting |
| Print Finish | Clear, solid color, or metallized logo | Enhances brand presentation on dispensary shelves |
What is a shrink band for pre-roll tubes wholesale without accurate layflat sizing? Bands that are too narrow will not slide over pop-top hinges, while oversized bands wrinkle during heating. Send your tube sample to our engineering department to confirm sizing.
常见问题
Why are shrink bands required on pre-roll tubes?
State and provincial cannabis regulations require tamper-evident seals to ensure products have not been altered prior to retail sale. What is a shrink band for pre-roll tubes wholesale provides an unbroken plastic collar that breaks upon opening. Ace quotes empty cones around USD $0.04–$0.06, MOQ applies.
How do you heat shrink bands onto tubes?
Commercial operations use conveyor steam tunnels, dry radiant heat tunnels, or manual industrial heat guns. What is a shrink band for pre-roll tubes wholesale shrinks in two to three seconds under controlled steam. In my experience, steam tunnels apply heat uniformly without scorching plastic tube bodies.
What is the difference between PET-G and PVC shrink bands?
PET-G is more recyclable, offers higher clarity, and tolerates steam tunnels better than PVC. What is a shrink band for pre-roll tubes wholesale made from PVC costs slightly less but is less environmentally friendly. I advise eco-conscious brands to select recyclable PET-G film for custom printed shrink sleeve orders.
Can custom artwork and logos be printed on shrink bands?
Yes, Ace prints full-color graphics, strain indicator colors, and metallic foil branding on heat shrink bands. What is a shrink band for pre-roll tubes wholesale can include printed QR codes and warning icons. We supply digital layout templates matching your specific tube diameter before printing cylinders are engraved.
What layflat width fits standard 116mm pre-roll tubes?
Standard 116mm pop-top plastic tubes typically use a 30mm to 32mm layflat width band. What is a shrink band for pre-roll tubes wholesale depends on cap hinge protrusion. I recommend measuring across the widest part of the squeeze hinge to prevent bands from snagging during manual sleeve placement.
