Common questions
How do crimped end tubes seal without tape?
Simply compress both ends of the tube together to create an airtight, tamper-evident seal. No tape, glue, or additional materials required. The spiral wound construction holds its shape, and tubes can be opened and resealed multiple times without degradation.
Are these tubes reusable and compliant with shipping regulations?
Yes. Kraft crimped end tubes are fully reusable and recyclable, meeting standard shipping and packaging compliance requirements. Their durable 3-ply spiral wound construction withstands repeated use, making them cost-effective for high-volume shipping operations.
What is the difference between the 18" usable length and actual tube length?
The 18" measurement represents the usable space inside the tube. Actual physical tube length is longer to accommodate the crimped end mechanism, which requires additional material for proper compression and sealing functionality.
Can I use these tubes for various product types?
Yes. The 2 1/2" diameter accommodates rolled documents, blueprints, posters, samples, fabric, and other cylindrical or rolled items up to 18" in length. The kraft material is durable enough for most industrial and commercial shipping applications.
