Q1.
What is a Horizontal form - fill and seal (HFFS) machine and why is it
called so?
A. This machine forms a tube by pulling sealable film over a forming
block by means of pairs of pulling and sealing rollers. Product is pushed
into the tube in a timed way. Ends of the tubes are crimped, sealed and cut
to form individual packs. In a horizontal machine the tube is drawn
horizontally and the product is pushed on a horizontal conveyor, hence the
name.
Q2.
How does the package formed on the machine look?
A. Pack formed on HFFS has a long seam running parallel to the
product along the centre line of the base of pack. Two end seals also called
Fin seals, complete the pack. This pack is also called pouch pack or pillow
pack because of its shape.
Q3.
What is Envelope folding?
A. As name suggests, end-folds in the pack are pressed against the
ends of the product and resemble a typical envelope. A regular shaped
product like soap bars can be neatly packed in this st
Q4.
What is the preferred way of packing biscuits?
A. Undoubtedly, pouch packing has certain advantages that makes it
ideally suited for biscuits. One, it gives hermetic seals i.e. the seals do
not allow any moisture penetration. Biscuits being very hygroscopic in
nature require this type of sealing on package. Two, this type of package is
very tolerant to size and shape of product, and biscuits vary a lot in size
and shape because of uncontrollable factors during production process.
Q5.
What are the various styles in which biscuits are wrapped in horizontal form
fill and seal machines? Do you offer these machines?
A. There are many favoured styles of packing biscuits in a pouch
shaped pack. 1. Biscuits placed in a tray and then wrapped: This is done for
delicate cookies and assorted varieties. These biscuits are arranged in
preformed thin plastic or paper trays. These trays are wrapped in HFFS
machine. Our model FINSEAL - 11 (wide body) can accept large width trays.
2. Biscuits in small piles: Also known as canteen pack, each pack contains
1 to 5 biscuits piled together and wrapped. The output of the machine can be
discrete packs or string together packs (no. of packs in a string). FINSEAL
- 11 HS model is meant for this job.
3. Large piles of biscuits: Also known as slug packs or "biscuits-on-edge"
pack, this machine takes long slugs of biscuits standing on-edge and wraps
in HFFS machine. Typically such a machine automatically meters out slugs of
the biscuits from a magazine (which is manually replenished) and directly
wraps it in a pouch shaped pack. iPac 21E model is meant for this type of
packing.
4. Family Pack: As name suggests, it is a larger pack containing 2 to 4
rows of slugs of biscuits. iPac 21FP model does this job.
Q6.
What wrapping materials are typically used on HFFS machines?
A. Typically laminates like Polyester / OPP, BOPP / BOPP, CPP /
BOPP, Polyester / PE or plain BOPP are used in HFFS machines. Advantage of
using laminates is that outer layer can be reverse printed to give a glossy
print appearance on the outside at the same time preventing printing
chemicals coming in contact with edible products like biscuits. All
materials used on HFFS must have sealable inside surface.
Q7.
What are the different ways of forming seals on HFFS?
A. If the inside surface has heat sealable material then application
of heat under pressure will make the seal. Cold sealable wrappers are also
available. For such materials mere application of pressure is enough to form
seals. Our machines can handle both types of wrappers.
O8.
What are the dimensions of the wrapper required to pack ur product?
A. Length of wrapper = Length of product + height or diameter of the
product +32m/m
Width of wrapper = 2 X (Width + Height of Product) + 32m/m in case of
rectangular product. = circumference of product + 32m/m for cylindrical
products.
Area of wrapper = Length X Width of wrapper
Q9.
How can the cost of wrapper be calc
A. Having selected the wrapper you need to know its gsm (weight in
grammes / sq.m) and rate per kg from the supplier of the wrapping material.
Cost of wrapper / piece = area in square mm x gsm x rate/kg x10-9
Q10.
We want to pack variety of biscuits. Are your various models adaptable to
different sizes and shapes?
A. All our models can be adjusted to accept different sizes of packs
if desired. Change over time for FINSEAL 11 and FINSEAL 11HS is about
15-20minutes.
Changeover time is 45 minutes to 1 hour for iPac 21FP and 30-45 minutes for
iPac 21E machines.
Q11.
What is Print Registration Unit? How does it work?
A. Printed wrapper comes in form of roll which is unwound on the
machine during the process of wrapping. Slight difference in pull length
will make the printed matter slip a little with respect to the product being
wrapped. This slip is cumulative and soon it will become noticeable and be
unacceptable. Print registration unit continuously detects the slip and
monitors the correction arrangement to ensure centrality of the printed
wrapper with respect to the product.
Q12.
What are the consumables required for HFFS machines made by you?
A. If a date or code printing device is used on the machine, then
inking cartridge or ink or rubber stamp are the consumable items. Cutting
knife used on the machine is a wearable item and may need replacement when
worn out.
Q13.
How many people are required to man the different HFFS machines offered by
you
A. FINSEAL 11: One feeder + one operator + one person to pack the
output from the machine in card-board (cb) boxes.
FINSEAL 11 HS: (1 or 2) + 1 + (1 or 2)
IPAC 21 E: 2 + 1 + 1
IPAC 21 FP: 2 + 1 + 1
Q14.
What are dimensions and layout plans for different HFFS machines offered by
you?
A. Please check our detailed catalogue for these machines.
Q15.
How do we order a machine with you?
A. After the enquiry stage and having satisfied each other with
suitability of our machine for your product we can send you a proforma
invoice giving FOB / CIF values and delivery period. For machines required
outside India, an irrevocable Letter of Credit payable at sight shall be
needed.
Q16.
How are the machines shipped abroad?
A We send our machines in sea worthy packing case as full container
load (FCL) of a 20ft. container.
Q17.
What about commissioning of machines?
A. Our service engineer(s) commission the machine at your works
wherever it is. Charges for the commissioning are mentioned in our offer.
