Many traditional courier bags uses PP & HDPE film for the printing, covering & shiny/transparent appearance such as magazine subscriptions, and the courier service uses Co-extruded film or LDPE/LLDPE and additives.
We observe the growth in Co-extruded film, which has many favorable properties:
1. Heavy Duty: Strong impact & Tensile strength. Multilayer takes different properties of different materials to be heavy duty and avoid over-elongation.
2. Dual Color & Barrier: Different colors & barrier layers to give different printability to outer layer and barrier property to inner layer.
3. Economic: Filler materials in the middle layer to cost down on raw material.
Apart from film, Several standard & optional features includes:
1. Pocket: Front pocket allow delivery & recipient to keep track on the content and delivery details, preventing documents on exposure to water.
2. Tape/glue strip/destructive strip: Easy closure & hard to tear. Some has destructive property which keep evidence of tampering of the inner content. Adhesive could be applied with Tape or sprayed on.
3. Tear-off receipt: Used in Russian market, a tear-off strip allows the delivery detail receipt be written and teared off by staff as a record.
4. Bubble film: a second inner layer of bubble film to protect delicate contents and provide shock resistance.
Many more could be inspired by the way of transportation and user-friendliness, and Plas Alliance Ltd. is happy to develop with you a unique application for this growing market.
