Packaging machine manufacturers need to know very specific details of your project in order to provide the most accurate recommendations and pricing.
Questions that need answers before proceed with the quote request:
1. Do you use premade pouches or rollstock fim?
A flexible packaging machine can either form your bags from a large roll of plastic film (called rollstock) or it can fill and seal bags that are already made. Rollstock film is large spool of flat plastic packaging film wrapped round a hollow core. Premade bags are prefabricated by a film supplier, meaning they arrive at your facility already formed into a bag shape. A packaging machine then fills and seals these bags.
2. What are your bags styles?
1. Pillow bags are the most widely-used and economical packaging format, comprised of two flat panels sealed together on the top and bottom with a vertical seal down the back.
2. Doypacks are stand-up pouches with an oval-shaped base. This premium bag type is becoming increasingly popular for specialty food products.
3. Quad seal bags have a rectangular bottom and can stand unassisted. This bag type has two side gussets and two panels joined together with four vertical seals, providing a more structured bag and modular look.
4. Flat bottom bags are similar to quad seal bags, featuring two gussets, but only have a single vertical seal.
5. Gusseted bags are similar to pillow bags but have side gussets, offering more internal space.
6. Three sides seal bags are flat pouches sealed on three sides.
7. Sachets are small, flat 4-side sealed packets. Think small single-serving packets of sugar and ketchup.
8. Stick Packs are very narrow pillow bags, used things like single-serve drink mixes.
3. Do you have any packaging speed requirements?
Speeds are usually given in bags per minute (bpm). This number represents how many finished bags the machine can complete per minute. The packaging machine speeds achievable for your particular project will depend heavily on your product and its properties, your plant environment, your bag type, and the skill of equipment operators.
4. What are your bags specifications?
Knowing the exact specifications of your bag or bags is vitally important to spec the appropriate packaging machine. Here's the information your OEM will ask for:
a. Package dimensions. For flat bags, width and length are all that's necessary. For bags that have gussets or stand up, width, length, and depth are required.
b. Package weights or volumes. For solids and powder products, how heavy is your filled package? For liquids, what is the volume of the filled package?
5. What are your product specifications?
A packaging system must be also tailored to the specifications of your product.
a. Solids: What is the average piece size (dimensions) and weight? Is the product sticky, dry, fresh, or frozen?
b. Liquids: What is its viscosity?
c. Powders: What is its bulk density? Does the product flow freely?
d. Filling temperature: When your product is filled into bags, will it be hot, frozen, or room temperature? (Expressed in degrees C or F)
