Types of Packaging – The Blister Packaging

“Blister Pack” Is a General Term That Describes Packaging That Uses a Process Known As Thermoforming. Thermoforming Involves Heating a Sheet Of Plastic To a Temperature Where It Can Be Easily Formed And Molded Into Any Desired Shape. The Term “Blister” Refers To The Pocket Of Thermoformed Plastic That Covers The Product.

Blister Packaging Refer To a Variety Of Packaging That Have a Pre-Formed Plastic “Pocket” Or “Shell” (Where a Product Sits Securely In Place) That Is Most Often Heat Sealed To An Adhesive Coated Paperboard Card Or Foil Backing (Think Single Dose Pills Or Lozenges).

There Are Many Types And Variations Of Blister Packs In Use In The Retail Market.

Face Seal Blister

a Flanged Blister That Surrounds The Product And Is Heat Sealed To a Piece Of Paperboard. The Seal Is Only On The Flange While The Rest Of The Card Stays Uncovered.

For Heavier Products a Larger Flange (Or Different Blister Style – See Below) Is Generally Used.

This Is a Very Common And Inexpensive Blister Pack Style If Your Volumes Are High Enough (25k – 500k).

Full Face Seal Blister

Similar To The Face Seal, This Blister Pack’s Seal Extends To The Entire Face Of The Card. This Offers More Durability And Strength To The Edges Of The Card (Prevents Bent Corners) And Reinforces The Hang Hole As Well. In Addition, It Offers a Higher Perceived Value Because It Looks Nicer Than The Standard Face Seal Blister, But Of Course Is More Expensive.

Tooling Costs For The Heat Seal Can Be Expensive For These Face Seal Blister Packs, But a “Trapped Blister” (See Below) Doesn’t Require Heat Seal.

Trapped Blister

This Type Is Similar To The Previously Mentioned Blisters, But Instead Of Heat Sealing The Blister To The Card, It Is “Trapped” Between Two Cards. The Top Card Is Die Cut To Fit The Blister Where The Product Sits. Since Trapped Blisters Do Not Use Heat Sealing, No Expensive Heat Seal Tooling Is Required.

Full Card Blister

In This Configuration, The Blister Extends To The Full Size Of The Card As In The Full Face Seal Blister, But Instead Of Being Sealed To The Card, It Has Flanges That Wrap Around The Card. The Card Is Simply Slid Into Place And Is Sometimes Secured With a Staple.

The basics of clamshells

  • Clamshell packaging secures product(s) between two hinged sheets of thermoformed plastic.
  • The plastic clamshell encloses the product on both sides and the plastic flanges (edges) can be heat sealed together.
  • Clamshells may be custom molded to follow the contours of an item, or serve as a clear plastic container for holding a number of small loose pieces together.
  • Tri-Fold clamshells or footed clamshells offer maximum versatility in merchandising. These packages can hang from a hook, stand alone on a shelf, or sit upright within a display or club store pallet.
  • A printed insert card sells the product with compelling graphics and product information while the clear plastic provides excellent visibility. When sealed on all edges clamshell packages are especially tamper and theft resistant.
  • Clamshells are recloseable and reusable if left unsealed.
  • Clamshell packaging is especially effective packaging option for heavy products, or items like electronics that are a target for theft.

Food storage container

Food storage containers are widespread in use throughout the world and have probably been in use since the first human civilizations.

In early civilizations cereal grains such as maize, wheat, barley etc. were stored in large airy buildings, often raised up from the ground to reduce infestation by pests and vermin. Ancient Egyptian and early Hebrew writings include reference to such buildings and their successors can still be seen in use in less developed countries and regions.

Smaller quantities of food were stored in baskets made from woven grasses or leaves and such designs have remained in use to the present day.

In more recent times but prior to the invention of the refrigerator many food products were stored in the home as preserves or pickles, often in heat sealed jars such as Kilner jars

In the modern developed world, a very wide range of food packaging and containers is now available made from many materials.

Plastic containers
Many products use low-density polyethylene formed into plastic bags or plastic boxes. There are many makers of plastic boxes some such as Tupperware and Lock & Lock are known throughout much of the developed world.

Metal containers
Longer term storage or storage of items needing a higher degree of protection from the elements may use sheet metal. A common form of such storage is the biscuit tin. See Canning.

Refrigerator
Perhaps the most ubiquitous domestic item of food storage is the fridge or fridge-freezer in which a wide variety of foodstuffs are contained and preserved through the use of low temperatures.

Disposable
Disposable foam food containers may be used for food or beverages.

Generally we use five kinds food storage containers in modern era:

Plastic food storage container.
Glass food storage container.
Stainless steel food container.
Ceramic food storage container.
Acrylic food storage container.

Fruit Punnet

A punnet pronounced is a small box for the gathering and sale of fruit and vegetables, typically small berries. The word is largely confined to Commonwealth countries and is of uncertain origin, but is thought to be a diminutive of “pun”, a British dialect word for pound, from the days in which such containers were used as a unit of measurement. The British Dictionary of National Biography, parenthetically in its entry for geneticist R.C. Punnett (1875–1967), credits “a strawberry growing ancestor devised the wooden basket known as a ‘punnet’ “.

Description
Punnets were originally a round woodchip basket but typically are now rectangular and made of plastic; increasingly moulded pulp and corrugated fiberboard are being used as they are perceived to be more sustainable materials. Decorative punnets are often made of felt and seen in flower and craft arrangements.
