Kerala Food Packaging Checklist Moisture First Food Grade Labels Shelf Life

Packaging looks simple from outside. Put the product in a pouch, seal it, print a label, sell it. In a factory, it is not that simple.

I am Haris Moideen. I run Vertex Blends, a spice and instant tea and coffee premix factory in Kumbidi, Palakkad. From my side of the packing table, the first question is not “Which pouch looks nice?” The first question is “What will damage this product first?”

For food packaging Kerala manufacturers cannot ignore the climate. Kerala humidity and the monsoon make moisture the biggest risk for many dry food products. If the pack fails there, the design, colour and branding do not matter.

This is the checklist I use when thinking about packaging for spices, powders, premixes and similar food products.

Good packaging starts with the product risk, not the pouch design.

1. Start with the product’s main enemy

Every product has one or two main enemies. The pack must fight those first.

For many dry products in Kerala, the enemy is moisture. This applies to:

• Spice powders

• Masala blends

• Instant tea premix

• Instant coffee premix

• Drink mixes

• Soup powders

• Other dry mixes

  
  

Moisture can cause caking, clumping, flavour loss and spoilage. Even a small amount of absorbed moisture can change the product feel. In Kerala, this risk is higher because the air is humid for much of the year, and the monsoon makes storage and transport harder.

For some products, the bigger issue is oxygen. Snacks, nuts and oils are more sensitive to oxidation. Oxygen can make them taste stale or rancid. These products usually need better oxygen barrier packaging.

Then comes light. Some products lose colour, aroma or quality when exposed to light for too long. Clear packs may look good on a shelf, but they are not always good for the product.

Heat processing also matters. If the product is hot-filled, retorted, pasteurised or packed soon after heating, the pack must handle that temperature and process. A pouch that works for dry room-temperature filling may fail during heat treatment.

Leakage is another direct risk. It is obvious for liquids, oils, chutneys and sauces, but it also matters for powders. A weak seal can leak fine powder during transport. Once powder comes out, air and moisture can go in.

Before choosing the pouch, bottle or tin, I ask:

• What will enter the pack and spoil the product?

• What will leave the product and reduce quality?

• Will the pack face heat?

• Can the seal survive handling and transport?

• Will the product smell, stain, leak or absorb odour?

  
  

This one step prevents many wrong choices.

2. Use only food-grade materials

Food packaging is not just a cover. It touches the food. So the material must be safe for food contact.

For food products, I look at options such as:

• Multilayer laminates

• Food-grade plastics

• Glass bottles and jars

• Metal tins

• Lined paper or lined board packs

  
  

The choice depends on the product, but the rule stays the same. Use food-grade material only.

In India, packaging must follow the Food Safety and Standards (Packaging) Regulations, 2018. These rules cover food contact materials and general safety requirements. For small manufacturers, this is where many mistakes start. A pouch may look strong, but that does not mean it is suitable for food contact.

Never use newspaper wrapping for food. Newspaper ink is not meant to touch food. It is not proper food packaging. This applies even for small local sale, trial packs or temporary packing.

For dry food, multilayer laminates are common because different layers do different jobs. One layer may give strength, one may block moisture, one may help sealing and one may support printing. The exact structure must suit the product.

For liquids and oils, the choice may move to bottles, jars, tins or suitable pouches. For premium or long shelf-life items, glass and tins are often used because they give strong protection when sealed properly.

The main point is simple. Do not buy only by look, thickness or price. Ask whether the material is approved for food contact and suitable for the product.

3. Match the pack to storage, transport and sale

A good pack must work after it leaves the packing machine. It must survive storage, transport, shelf display and use.

I look at three areas.

Storage conditions matter. Will the product sit in a humid store? Will cartons be stacked high? Will the packs face heat during transport? Will the retailer keep them near sunlight or in a closed room?

Transport matters. Packs rub against each other. They get compressed inside cartons. They may travel through rain, heat and careful or rough handling. A beautiful pouch with weak sealing or poor puncture resistance will fail here.

Sale format matters. A product sold in a small sachet has different needs from a product sold in a jar or family pack. A single-use sachet must tear cleanly and protect until opening. A larger pack may need resealability or a stronger structure.

At Vertex Blends, our Saudi export spice sachets use a 3-side seal, 7 x 10 cm, 85-micron, matte, 3-layer laminate pouch. That pack choice is not random. It is matched to the product, sachet size, sealing method, handling and export requirement.

This does not mean every spice product needs the same pouch. It means the pack must be chosen for the job.

For example, a small chilli powder sachet, a 500 g masala pouch and a glass jar of paste cannot follow the same thinking. The product, fill weight, shelf life, sale channel and handling decide the pack.

Use this as a simple food packaging checklist before approving a pack:

• Will the material protect against the main risk?

• Will the seal hold during transport?

• Will the pack shape fit the carton?

• Will the consumer be able to open and use it properly?

• Will the label area be enough for legal information?

• Will the pack suit local sale, retail shelf or export?

  
  

Good spice packaging is not only about aroma lock or attractive printing. It must protect the powder in real Kerala storage and transport conditions.

4. Work backwards from target shelf life

Shelf life should not be guessed after buying the pouch. Decide the target first, then choose the packaging.

Common starting points are:

• 30 days

• 90 days

• 180 days

  
  

A short shelf-life product may work with a simpler pack if storage is controlled and distribution is fast. A 180-day product usually needs stronger protection, better sealing and more checking.

For dry powders, moisture barrier is the main point. For nuts, snacks and oils, oxygen barrier becomes more important. For light-sensitive products, opaque or light-blocking packs may help. For products that lose aroma, the pack must hold volatile compounds better.

Shelf life is affected by many things:

• Raw material quality

• Moisture level before packing

• Packing room conditions

• Packaging barrier

• Seal quality

• Storage temperature

• Handling

• Distribution time

  
  

Packaging cannot fix a bad product. If the powder already has high moisture, even a good pouch may not save it. If the seal temperature is wrong, even good laminate can fail.

Work backwards like this:

1. Set the target shelf life.

2. Identify what changes first in the product.

3. Choose material with the right barrier.

4. Confirm sealing quality.

5. Store test packs under real conditions.

6. Keep records before scaling.

   
   

For a new product, avoid printing huge quantities of pouch before the pack is tested. If the barrier or label changes, printed stock can become waste.

Seal quality is part of shelf life, especially for dry powders in humid weather.

5. Check the label before printing

Label mistakes are costly. Once the printed pouch is made, correction is difficult.

For India, labels must follow the Food Safety and Standards (Labelling and Display) Regulations, 2020. The label should include the required information for that product and pack size.

For most packaged foods, check for:

• Ingredients

• Net quantity

• Nutrition information

• FSSAI logo and licence number

• Veg or non-veg symbol

• Date markings

• Batch or lot details

• Allergen information where applicable

• Name and address details as required

• Instructions for use or storage where needed

  
  

Do not treat this as artwork only. The label is a legal document on the pack.

Nutrition values must be correct. For our export labels, we got nutrition values lab-tested before finalising the label. That is the safe way to do it, especially when the product is going outside India or when the label has detailed nutrient claims.

For Saudi export, Indian rules are not enough. The pack must also meet Saudi requirements. Food export packaging Saudi Arabia work needs checking of SFDA and SASO rules, Arabic labelling and product-specific requirements. The Arabic label must be handled carefully, not added at the last minute without review.

I also check practical label issues:

• Is the font readable?

• Is the print area enough?

• Will the seal area cut into the label matter?

• Is the date printing space clear?

• Can batch number and date be printed cleanly?

• Will matte or glossy finish affect readability?

  
  

FSSAI packaging rules and labelling rules are separate areas, but both affect the final pack. A safe pouch with a wrong label is still a problem.

6. Add small extras only when they solve a problem

Small packaging extras can help, but they should have a reason.

Desiccants may help products that are highly moisture-sensitive, if the pack and product format allow it. They must be food-safe, suitable for the pack and clearly handled so they are not eaten by mistake.

Tamper-evident seals help show whether a product has been opened. This can be useful for bottles, jars, some tins and certain retail packs.

Nitrogen flushing can help products that are sensitive to oxygen, such as snacks, nuts and some high-fat products. It is not a decoration. It needs proper equipment and sealing. If the seal is poor, flushing will not help.

Food-safe inks matter because printing is part of packaging. The ink system must be suitable for food packaging use. This is especially important when printing on flexible laminates or when packs are stacked and handled.

Other extras may include:

• Tear notch

• Zip lock

• Spout

• Induction seal

• Inner liner

• Outer carton protection

  
  

Each extra adds cost. Use it when it protects the product, improves safe use or supports the sale format. Do not add features only because another brand has them.

7. Ask suppliers for documents before approving the pack

Do not rely only on verbal assurance from the packaging supplier. Ask for documents.

Before I approve a packaging material, I prefer to ask for:

• Food-grade declaration

• Material structure

• Barrier specifications

• Test reports where available

• Thickness details

• Seal layer information

• Printing ink suitability where relevant

  
  

For multilayer laminates, “85 micron” alone is not enough. Thickness tells only part of the story. The structure and barrier properties matter more. Two materials with similar thickness may perform differently against moisture or oxygen.

Ask what the layers are. Ask whether the material is suitable for the product. Ask whether the supplier can support repeat orders with the same structure.

Also check the practical side:

• Minimum order quantity

• Lead time

• Printing quality

• Shade variation

• Roll or pouch supply format

• Compatibility with your filling and sealing machine

• Carton packing method

  
  

Small manufacturers often face problems because packaging is ordered late. Packaging should be part of product development, not the final step after recipe, logo and price.

Quick reference table for common food packs

This table is a starting point. Final selection should match the exact product, process, shelf life and sale channel.

Product type	Main risk	Usual pack

Instant tea and coffee premix	Moisture, caking, flavour loss	High-barrier laminate pouch or sachet
Snacks and fried items	Oxygen, moisture, breakage	Nitrogen-flushed laminate pouch where needed
Nuts and dry fruits	Oxygen, rancidity, moisture	Barrier pouch, jar or tin
Oils	Oxygen, light, leakage	Food-grade bottle, tin or suitable pouch
Pickles and pastes	Leakage, oil migration, acidity	Glass jar, food-grade plastic jar or suitable pouch
Bakery dry mixes	Moisture, infestation, handling damage	Lined paper/board or laminate pouch
Ready-to-use liquid products	Leakage, heat process, shelf life	Bottle, jar, retort pouch or process-suitable pack

Packaging decisions I would not rush

I would not rush these choices:

• Switching from local sale to export pack

• Moving from short shelf life to 180 days

• Changing from hand sealing to machine packing

• Changing pouch structure only to reduce cost

• Printing labels before nutrition and legal review

• Using transparent packs for sensitive products

• Buying large stock before trial packing

  
  

Packaging errors are expensive because they reach the market with the product. If the pack fails, the product gets blamed first.

A good pack should do five things well:

1. Protect the food.

2. Seal properly.

3. Carry the legal label.

4. Survive storage and transport.

5. Fit the way the product is sold and used.

   
   

If it does these five things, design and finish can be built on top of it.

FAQ

What is the first thing to check when choosing food packaging?

Check the product’s main risk. For dry powders in Kerala, it is usually moisture. For snacks, nuts and oils, oxygen may be the bigger risk. The pack should be chosen for that risk first.

Can I use the same pouch for all food products?

No. A pouch that works for spice powder may not work for oil, pickle, snacks or premix. Match the material, seal and barrier to the product, storage, transport and shelf life.

Should I finalise the label before or after testing the pack?

Finalise the legal content before bulk printing, but test the pack early. Nutrition values, FSSAI details, date area, allergens and export language requirements should be checked before printing large quantities.
