Single Serve FAQ                                                                              

What is thermoforming, and how do you do this? 

Thermoforming is the process of taking a sheet of plastic, and shaping it with heat. We offer the choice of thermoforming on one side – leaving the other flat, or on both sides to
provide symmetry. If your product requires a food barrier, it is applied inline, and formed with the outer shell.


So how does this 7-step single-serve packaging process work.
Sarong’s ground-breaking process means that we
1) feed plastic film (& barrier),
2) thermoform,
3) join the halves,
4) fill with your product,
5) seal,
6) label (if nesscessary), and
7) cut.
All inline – without manual intervention. That means speeds of up to 9600 units per hour! Those Italians have a long history of loving fast machines!


What products are suitable?
Liquids and gels. Viscosity can be an issue, so while honey will work, peanut butter will not. Liquids like chocolate, which solidify when cooled can also work. Creams, sauces, syrups – all can work very well. If you are concerned about the viscosity of your product, we’ll test it. Solids within liquids will depend – specks in suspension works fine, but tarragon leaves in vinegar do not. Both oxygen and moisture barriers are available, but we don't recommend highly reactive materials. We are currently avoiding fragrances, in accordance with our food handling accreditations.


What size range can you accommodate?
5 to 50 ml is easy with our standard setup. With special feeders, we can get accuracy to .5 ml, and as high as 75ml.


Tell me about the packaging material?
The type of material used determines maximum thickness. For PET it’s 500 microns, for PP/PE 400 microns. This thickness ensures that the final package is easily squeezed, yet maintains complete integrity. Printing or labeling – what are my choices? Your final package can be clear, translucent or opaque. 7-color printing works great on the thermoform film. If a label is more suitable for you, it can be applied in the same inline process.


What shapes are possible?
Choose symmetrical, or flat on one side. The rest is up to your imagination. Do you have a distinctive bottle shape to emulate? There will be setup fees for new shapes, of course, and it takes some time to produce the forms. We also have some standard forms, ready to roll at a moments notice.  These are available as 2.5 to 5 ml, and 7.5-15 ml. Check with us to find out more, as this changes quickly.


Bottle/jar replacement package integrity?
There are no caps or lids required, and the sealing process ensure 100% integrity – no leakers? If you’ve ever had a case of product spoiled by one leaky bottle, you’ll appreciate guaranteed quality.


Minimum run?
Well, we’ll have to chat about this. Understand that this is a high speed process that can produce close to a quarter million units in a day! But of course, if you had high volumes, you’d probably just buy Sarong equipment for yourself! We also have some interesting options to explore for smaller test runs….


Prototype shapes & artwork?We have local engineering and design able to produce prototypes to show the boss.


What’s this about multi-packs?

Let’s skip the easy stuff like matching marinade & sauce – too simple to discuss. We can produce a perforated strip of six different flavours or colors. Up to nine if they're all the same! We can package oil and vinegar – in differing volumes! Now let your imagination soar. Imagine a cooking pack, with marinade, basting sauce, and multiple dips.


Merchandising options? 
OK – we’re Econopac, and handle merchandising every day. So yes, your single serve package can be clip stripped or have a bottle hangar, but we can also glue it to card stock, create kits & displays, over-label, over-wrap, carton, bundle, manage for direct mail....
