Dry Food & Snack Packaging

People love snacks, so we help meet the packaging needs of today’s consumer.

SNACK PACKAGING THAT LOCKS IN CRISPNESS

Crackers, chips, nuts, cereals and bakery goods can become soggy in moist environments or just get stale and tossed out before their time.

The packaging of snack foods demands specific requirements to maintain freshness. These requirements may include barrier to light, oxygen, or moisture, as well as toughness and sealability.

Fortunately, smart packaging design using Dow and DuPont materials can keep snack foods fresh longer.

Snack Packaging Materials Designed for the Job
From dry food that requires a barrier to moisture to those with stringent flavor and odor requirements, Dow has a broad range of products and solutions to match the packaging need. Dow's snack packaging materials and technologies have been perfected over the years through collaborative efforts with brand owners, retailers and converters.

Shelf appeal and the tactile feel of a package are major concerns with snack food. Dow and DuPont resins, adhesives and coatings for snack food packaging are designed to optimize a package’s look and feel as well as its performance.

Range of Durability Options
Dow and DuPont resin combinations and experienced product development support enable brand owners and converters to tailor the hardness, stiffness, or flexibility characteristics of packaging for better food presentation and protection against damage.

High Hot Tack Strength
Dow and DuPont packaging resins, including and DuPont™ Surlyn®, are scientifically engineered to provide increased hot tack strength for sealing and superior performance under a broader range of sealing temperatures. This helps maintain higher packaging line speeds and reduces the number of seal failures for greater moisture vapor control.

Excellent Foil Adhesion
DuPont™ Surlyn®, DuPont™ Nucrel®, and DuPont™ Appeel® provide a strong, consistent seal to aluminum packaging, forming an excellent moisture barrier for a variety of snack and dry food applications.

Controlled Opening and Unrivalled Seal-Through
Surlyn® can be modified to control its opening force and provide a more consistent peel compared to other resins. Its opening force can be controlled by varying the thickness of the Surlyn® layer, while continuation peel force can be controlled by mixing different grades of Surlyn® resin. This allows Surlyn® to deliver:

  • Excellent tear propagation properties for directional tear
  • Excellent peelability for easy opening
  • Stable peel performance over time
  • Reduced potential for seals to open during shipping and handling due to its high-performance seal characteristics
  • Seal through powder contamination, maximum hot tack, low Seal Initiation Temperature (SIT), and the broadest range of operating temperatures

Powdered Food Protection
For dehydrated foods, such as coffee, soups, soluble drinks, bakery mixes, and sauces, using Surlyn® in aluminum-based pouches provides:

  • Superior seal integrity, sealing through powder, gussets, and folds
  • Higher line speeds due to excellent machinability, stiffness, and low seal initiation temperature
  • Excellent protection against moisture and oxygen
  • Fewer taste and flavor issues due to the minimization or elimination of primers
  • Easy-tear opening

Cost Savings and Downgauging Potential
Only Surlyn® is able to combine stiffness and sealability at low temperatures. The direct adhesion of Surlyn® to aluminum, as well as its superior barrier performance with relation to oil, results in a greater resistance to delamination without the use of solvent-based primers or glues. Cereals and snacks packed in stand-up pouches eliminate the extra cost of the box. These combined benefits can lead to snack packaging material cost reduction. Surlyn® can also offer substantial downgauging potential, due to its toughness, which reduces puncture rates during handling and transportation, and its stiffness, which reduces overall thickness while still allowing for good machinability.
