The seal layer is closest to the drink. It keeps liquid from leaking out. The barrier layer stops moisture and oxygen. The tie layer holds all the layers together. The structural layer makes the carton strong. The outer layer is for printing labels. The coating protects the outside from damage.
How thick each layer is matters. It changes how well the packaging works. The surface layer stops water and oil. The core layer gives strength. The bottom layer stops leaks. These layers help the packaging last longer.
The layers stick together very well.
Water does not get in easily.
The packaging stays strong because of high bonding.
Paperboard is the main part of liquid packaging board. It makes up most of the carton. You see paperboard in milk cartons and juice boxes. Paperboard gives the carton its shape and strength.
| Type of Paperboard | Common Uses |
|---|---|
| Liquid Packaging Board | Milk cartons, juice boxes, pouches |
Manufacturers cover paperboard with thin plastic layers. Sometimes, they add aluminum for better protection. Tetra Pak® milk pouches have six layers. About 70% of the pouch is paperboard. This design keeps drinks fresh for a long time.
Additives make paperboard stronger and better. Wet strength agents help cartons stay strong when wet. They stop the carton from falling apart if it gets damp. Curesan products help printing look good and make coating stronger. Wet rub resistance keeps cartons clean and easy to read.

Strong barriers keep drinks safe. The layers block moisture, oxygen, and light. Materials like aluminum foil and special plastics help do this.
| Material Type | Barrier Against | Effectiveness |
|---|---|---|
| Multi-layer barrier preforms | Oxygen | Transmission rates between 0.1-10 cc/m²/day |
| Vacuum-deposited AlOx/SiOx laminate | Oxygen, Water Vapor | OTR below 0.05 cm³ m⁻⊃2; day⁻⊃1;, WVTR below 0.01 g m⁻⊃2; day⁻⊃1; |
| Fibre-based laminates with non-foil barriers | Oxygen, Water Vapor | Retains foil-class OTR and WVTR, increases renewable content |
Packaging must meet strict rules. The moisture vapor transmission rate should be less than 10 g/100 in⊃2;/day. The Cobb Test for water absorption should be below 1 g/m². Grease and oil resistance needs a Kit Test rating of 10 or more. These rules make sure drinks stay fresh and safe.
Tip: Strong barriers help keep drinks fresh and cut down on waste.
Liquid packaging board is great for foods like milk, juice, and soup. The layers stick together well and stop leaks. The packaging blocks moisture, oxygen, and light. This keeps drinks tasting good and safe.
Workers begin with wood chips. They heat the chips and add chemicals. This makes pulp for the packaging. Machines press and dry the pulp. The pulp turns into strong paperboard. Molten polyethylene goes on the paperboard. This makes a waterproof layer. Printers put designs and logos on the board. Machines cut the board into blanks. These blanks are the base for cartons. Workers fold and seal the blanks. This forms the final packaging.
Quality control is important at every step. Workers check thickness and coating. They test for moisture resistance. These checks help keep drinks safe inside the carton.
There are many ways to coat and laminate packaging. Metalized film lamination makes products look shiny in stores. Extrusion coatings block moisture, gas, grease, and aroma. Adhesive lamination makes cartons stronger. Water-based coatings are better for the environment. Corona treating gets surfaces ready for coating and lamination.
Different coatings change how you recycle packaging. Water-based coatings make recycling easier. They also help the environment. UV coatings need more energy and slow down recycling. Film lamination protects drinks but makes recycling harder. You must separate plastic from paper. Picking the right coating helps lower harm to the planet.
There are different ways to form cartons. Gable top cartons have a pointed top that closes tight. These cartons use recyclable materials. They stay strong during shipping. Plastic-coated paperboard gives a moisture barrier. It keeps drinks fresh. Brick cartons use layers of low-density polyethylene and paperboard. These cartons block moisture and keep out impurities. Drinks last longer in these cartons.
| Aspect | Description |
