Envelopes, fixed bags, flexible bag lengths or fully customised packaging solutions.
In general, there are four solutions for packaging in flexible material.
- LDPE shipping envelopes (fully manual packing)
- Semi-automatic packaging of layflat tubing: each bag has the ideal size for the product to be packed
- Semi-automatic packaging in bags on a roll: each bag has the same size
- Automatic packing on side-sealing machine
When using LDPE envelopes or pre-perforated bags on a roll, the dimensions are fixed, of course depending on the size of the envelope or film roll used. Packing in shipping envelopes is a completely manual process and is therefore very labour-intensive.
Semi-automatic pre-perforated bags
Packing with pre-perforated bags on rolls is a semi-automatic process and therefore less labour-intensive. When pre-perforated bags on a roll are packed, the film is automatically fed in and sealed on one side (top) after the filling process.
Semi-automatic packaging with layflat tubing
Semi-automatic packaging with layflat tubing involves a variable bag length. The length of the packaging is variable because both the top and bottom are cut off and sealed. The length of the packaging therefore corresponds to the size of the product to be packaged.
Automatic side sealing
There are also automatic packaging machines for fully customised packaging (side sealing machine), in which case the sealing and cutting takes place around the product. This way of packaging is expensive in terms of machine investment, and there is also a lot of material loss. These machines often have a higher capacity. The film (half-tube film: film opened/doubled on one side) is loaded into the machine and all residual material is punched (cut) around the product. This type of automatic side-sealing machine also has another disadvantage: for products that are packed singly or in a limited number (stacked 2 to 3 max.) it works very well, but if more stacked units are supplied, they cannot be processed due to the limited height of the product in transit and instability of the stack of products to be packaged.
Flexibility with Speedpack Hybrid
The Speedpack Hybrid works with both fixed bag length and flexible bag length (i.e. hybrid). This ensures the necessary flexibility, but also the optimum ratio in terms of costs, application possibilities and material savings. In addition, our customers save space because the hybrid (fixed bag on roll & flexible layflat tubing packaging) character actually combines two machines into one.
In addition to packaging flexibility, the Speedpack Hybrid is also ideal for identifying the packaging. This concerns printing, labelling and/or coding the packaging.
