Particular implementations of the subject matter described in this specification can be implemented so as to realize one or more of the following advantages. Implementations provide a packing pouch with reusable components. For example, implementations reduce single use plastic components in shipping pouches, and thus, reduce plastic waste entering the environment. Recycling efficiency may be improved by easily separating independently recyclable materials. Implementations may improve shipping monitoring device longevity by providing a durable protective casing. Implementations may improve shipping within a distribution channel for sending and receiving shipments by improving the likelihood that shipping documents are kept with corresponding shipments throughout the journey through the channel. Implementations may reduce the lost or missing of shipments within a distribution channel.
The details of one or more implementations of the subject matter described in this specification are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.
Like reference numbers and designations in the various drawings indicate like elements.
A distribution channel for sending and receiving shipments generally employs shipping documents to route, sort, and track various shipments flowing through the channel. Shipping documents include, for example, air waybills, shipping labels, invoices, packing lists, and other paperwork related to a shipment. The shipping documents are placed inside a pouch that is attached to a receiving surface such as a package, box, carton, or other container to be shipped through the channel. To insure proper sorting, tracking, import/export, and ultimately, delivery, it is important to keep shipping documents with the shipment throughout the journey through the channel. At the destination, the recipient breaks opens the pouch and removes the shipping documents.
The shipping documents can include items such as packing slips or monitoring devices. Monitoring devices can be larger or shaped such as to require additional protection while enclosed in the pouch. Package monitoring devices that can be placed in a packing pouch include, but are not limited to, devices which monitor location, temperature, humidity, atmospheric pressure, tilt angle, shock, or vibration.
While most shipping packages are made of recyclable corrugated boards, the traditional adhesive plastic pouches and packing list envelopes make recycling shipping packages difficult and costly. The plastic packing pouches and envelopes must be removed before the cardboard board package can be recycle. However, traditional packing pouches and envelopes often stretch, tear, and rarely come off the package in one piece. If not recycled, those plastic pouches and packing list envelopes may be sent to land-fills directly, end up at land-fills, or are dumped into the ocean where they remain and do not be decomposed, polluting the land or ocean. Additionally, these plastic materials may contaminate water and/or injure fish or other marine animals.
As shown in
The shipping package 104 is one example of a shipping container to which the recyclable shipping pouch 102 can be affixed.

The monitoring device 110 senses a condition or multiple conditions of the shipping container. For example, the monitoring device 110 can track and monitor location, temperature, humidity, atmospheric pressure, tilt angle, shock, or vibration. The monitoring device 110 can include an electronic log or electronic receiver to sense electronic signals. For example, the monitoring device 110 can include an electronic receiver to receive satellite signals to determine the shipping container location. The monitoring device 110 can include an electronic transmitter to transmit shipping container conditions or location. The monitoring device 110 can include machine readable code 112 which contains information regarding a content of the reusable recyclable packing pouch 102 or the shipping package 104.
