Many buyers choose roll film by price first. This can cause sealing problems, machine stops, film waste, and delivery delays1.
To choose roll film for VFFS and HFFS packaging machines, I first check the product, bag style, machine type, filling speed, sealing method, and shelf-life needs. VFFS suits vertical filling products. HFFS suits horizontal flow wrap products.
From my experience at IMIPAK, the right step is simple. Choose the right packaging machine first. Then choose the roll film structure for that machine.
What Are the Different Types of Packaging Films?
Packaging film has many types. Each type has a different role in printing, sealing, strength, and barrier.
Common packaging films include PE, PP, PET, BOPP, CPP, PA, aluminum foil film, metalized film, and laminated film. Food packaging often uses laminated roll film because one single film cannot meet every need.
Main Film Types
| Film Type | Common Role | Main Use |
|---|---|---|
| PE | Inner sealing layer | Coffee, powder, snacks |
| PP | Clear and stiff film | Snacks, biscuits, candy |
| BOPP | Printing layer | Flow wrap, snacks |
| CPP | Sealing layer | High-speed packaging |
| PET | Outer printing layer | Strong printed roll film |
| PA | Puncture resistance | Heavy or sharp products |
| VMPET | Barrier layer | Coffee, nuts, dry food |
| Aluminum foil | High barrier layer | Long shelf-life food |
I do not choose film by name only. I always check the product and machine first. Coffee needs aroma protection. Nuts need moisture protection. Powder needs stable sealing. Wet wipes need leak resistance.
What Are Laminates in Food Packaging?
Laminates are common in food packaging because one layer is rarely enough.
Laminates are multi-layer packaging materials made by bonding different films together. Each layer has a job, such as printing, strength, barrier, or sealing. Laminated roll film is widely used for VFFS and HFFS packaging2.
Common Laminate Structures
| Structure | Common Use | Main Benefit |
|---|---|---|
| PET/PE | Powder, dry food | Printing and sealing |
| BOPP/CPP | Biscuits, snacks | Clear look and fast sealing |
| PET/VMPET/PE | Coffee, nuts | Better barrier |
| PET/AL/PE | High-barrier food | Strong oxygen protection |
| PA/PE | Heavy food | Puncture resistance |
The outer layer helps printing and strength. The middle layer helps barrier. The inner layer helps heat sealing.
At IMIPAK, I customize laminate structures based on product type, machine speed, shelf-life need, and packing style. A good laminate is not always the thickest one. It is the one that runs well and protects the product at the right cost.
What Is a VFFS Packaging Machine?
VFFS is common for loose food products that can fall into the bag from above.
A VFFS packaging machine is a vertical form-fill-seal machine. The roll film moves from top to bottom. The machine forms the bag, fills the product from above, and seals the package.
How VFFS Works
VFFS means vertical form-fill-seal. The machine pulls roll film downward. It forms the film around a tube. Then it seals the back, seals the bottom, fills the product from the top, seals the top, and cuts the bag.
Many IMIPAK coffee packaging customers use VFFS machines. VFFS is widely used for coffee beans, ground coffee, nuts, snacks, powder, rice, grains, and pet food3.
| Product | Common Bag Type |
|---|---|
| Coffee beans | Center seal bag, stand up pouch |
| Nuts | Pillow bag, stand up pouch |
| Powder | Center seal bag |
| Rice and grains | Block bottom or center seal bag |
| Pet food | Large pouch or center seal bag |
For VFFS roll film, I pay attention to film tension, sealing strength, thickness, and barrier. If the film is too soft or too stiff, the machine may not run well.
Which Types of Food Packaging Would PP Film Be Suitable For?
PP film is useful, but it is not suitable for every food package.
PP film is suitable for dry food, snacks, biscuits, candy, bakery products, and some flow wrap packs4. It is often used as BOPP or CPP in laminated film for clarity, stiffness, printing, and sealing.
BOPP is often used as the printing layer. CPP is often used as the sealing layer. PP-based films are common in HFFS packaging because they run fast and create neat pillow packs.
| Food Product | Common Film |
|---|---|
| Biscuits | BOPP/CPP |
| Chocolate bars | BOPP/CPP or PET/CPP |
| Bread | BOPP/CPP |
| Cakes | BOPP/CPP |
| Candy | BOPP/CPP |
| Snacks | BOPP/CPP |
For coffee or nuts with longer shelf life, simple PP film is usually not enough. I may suggest PET/VMPET/PE or PET/AL/PE for better oxygen, moisture, and aroma protection5.
What Are the Five Types of Films?
Many buyers hear too many film names. I usually explain them by function.
The five common types of packaging films are PE film, PP film, PET film, PA film, and barrier film. Food roll film often combines these films into one laminated structure.
Five Film Types in Simple Words
| Film Type | Main Function |
|---|---|
| PE | Heat sealing |
| PP | Clarity and stiffness |
| PET | Printing and strength |
| PA | Puncture resistance |
| Barrier film | Oxygen, moisture, and light protection |
For example, coffee beans may use PET/VMPET/PE. Biscuits may use BOPP/CPP. Powder may use PET/PE. Pet food may need stronger PET/PE or PET/VMPET/PE.
The best structure is not always the most expensive one. The best structure should match the product, machine, and budget6.
What Are the 7 Types of Packaging?
Roll film is one type of packaging, but buyers should understand the bigger packaging picture.
The seven common types of packaging are flexible packaging, rigid packaging, paper packaging, glass packaging, metal packaging, plastic containers, and transport packaging7. For VFFS and HFFS machines, flexible roll film is the main choice.
Seven Packaging Types
| Type | Example |
|---|---|
| Flexible packaging | Roll film, pouches, bags |
| Rigid packaging | Trays, tubs |
| Paper packaging | Cartons, paper bags |
| Glass packaging | Jars, bottles |
| Metal packaging | Cans, tins |
| Plastic containers | Cups, boxes |
| Transport packaging | Cartons, pallets |
At IMIPAK, we focus on flexible packaging pouches and laminated roll film. Flexible roll film saves space, supports automation, and allows custom printing8. It is very useful for food factories with stable production.
How Should I Choose Between VFFS and HFFS Roll Film?
The machine choice should come before the film choice9.
I choose VFFS when the product can drop vertically into the bag10, such as coffee beans, nuts, powder, rice, grains, and pet food. I choose HFFS when the product moves horizontally, such as biscuits, chocolate bars, bread, cakes, and wet wipes.
VFFS vs HFFS
| Factor | VFFS | HFFS |
|---|---|---|
| Film direction | Top to bottom | Horizontal |
| Product movement | Drops from above | Enters from side |
| Common bag | Center seal, stand up, pillow | Pillow pack, flow wrap |
| Best products | Coffee, nuts, grains, powder | Biscuits, chocolate bars, bread |
| Main value | Good for loose products | Good for shaped products |
VFFS roll film moves downward. The machine forms the bag first, then fills product from the top. HFFS roll film moves sideways. The product also enters sideways, then the machine wraps and seals it.
IMIPAK provides one-stop customized service for different customers. I check the product, machine model, roll direction, film width, bag style, printing design, and material structure before production.
Conclusion
Choose the machine first, then choose the roll film. VFFS fits vertical filling products. HFFS fits horizontal flow wrap products. The best film must match product, machine, and cost11.
