Packaging Material: Plastic
What are Biodegradable Plastics?
Biodegradable plastics are plastics which microorganisms (bacteria and fungi) can be decomposed into water, carbon dioxide (CO2) and other biomaterials.
It is important to stress that biodegradable plastics are not necessarily manufactured biomaterials (eg, plants)
Many biodegradable plastics are made from petroleum as conventional plastics.

In the late twentieth century the price of oil fell, and fell just as interest in biodegradable plastics
In recent years this trend has reversed, as well as producing a rise in oil prices has been a growing awareness that oil reserves are being depleted at an alarming rate.

Within this context, there is a marked increase in interest in scientific and industrial research for the production of biodegradable plastics or PDEs (environmentally degradable polymers and plastics).
Bubble Cushioning & Bubble bags
Bubble wrap is a flexible plastic sheeting containing numerous small air pockets, used in cushioning items during shipment.
Standard average bubble diameter is 6.0 – 25.4 mm and height about 4 mm.
It's lightweight, water resistant, reusable non-scratching and commonly used for packing fragile items.
Also called 'bubble pack'.

Bubble Wrap was created by two engineers, Alfred Fielding and Marc Chavannes, in 1957.
The story begins in a garage in Hawthrone, NJ where two engineers were trying to make a plastic wallpaper with a paper backing. Surprisingly, this product did not take off but they quickly realized, that their invention could be used as a cushioning material for packaging. And, later pair founded Sealed Air Corporation in 1960
How Bubble Wrap packaging is made?
1. Bubble Wrap starts as polyethylene (plastic) resin, in the form of beads about the size of pea gravel

2. The beads go into an extruder - a long cylinder with a screw inside that runs its entire length.

3. As the screw is turned, heat builds up and the resin melts into a liquid that is squeezed out of the cylinder into two stacked sheets of clear plastic film.
4. One layer of the film is wrapped around a drum with holes punched in it, and suction is applied drawing one web of film into the holes that form the bubbles.

5. The second layer of film is then laminated over the first so that when the two films are joined, they stick together and trap the air in the bubbles.

6. After this, some manufacturing companies such as Sealed Air started using a Saran coating to seal the air in the bubbles.
Light weight - reduces freight and packaging costs
Transparent – enabling visual inspections of the product
Moisture resistant
Protecting surface against abrasion
Easy to use
Good insulation properties
Elastic and strong
Multiple use
Easy to trim by hand tools and trimming machines

Generic bubble wrap's negative aspects include the product's biodegradability, disposable means, storage and fire hazards.

Toxic waste

Environmental problems

Storage difficulties

Flammable hazards
Main Types
Bubble bags: Quick & Easy to use, Ideal for faster wrapping

'Plain Bubble Bags' – to protect general purpose items & 'Antistatic Bubble Bags' – to protect sensitive electronic parts and components from static damage

Lightweight/Standard bubble wrap rolls: Used for cushioning lightweight products, interleaving and surface protection

Medium duty bubble wrap rolls: Used for cushioning of medium weight products, interleaving

Heavy-duty bubble wrap rolls: Used for cushioning heavier items such as shipping motors, compressors, valves etc.

Bubble mailers or Bubble envelopes: Used to protect CD’s, DVD’s, videocassettes, jewelry, antiques, valuables in shipping

To protect any item in transit packaging - for cushioning lightweight, medium weight or heavy weight products

Main Use
Plastic: Primary and Secondary package
The first plastic occurs in 1860, was the American inventor Wesley Hyatt who developed pressure processing piroloxina a low cellulose nitrate nitration pretreated with camphor and a minimal amount of solvent alcohol.

1860-1944, synthesized a polymer of commercial interest, no electricity condition was resistant to water and solvents, per easily machinable. Bakelite, the first synthetic plastic.
How Plastic is made?
The plastic is applied to the substances of similar structures that lack a fixed point of evaporation and held over a temperature range of elasticity and flexibility properties allowing mold them and adapt them to different shapes and applications.

Certain synthetic materials obtained by polymerization or multipliccation phenomena of semi-natural carbon atoms in the long chain molecules of organic compounds derived from petroleum and other natural substances.
It burns easily to contain carbon.

Shockproof (compact objects).

Very light.

Brittle, elastic and molded into bags.

Protect the product of the environment for preservation.

Main Characteristics
How Plastic is made?
Main uses
High density polyethylene (HDPE / HDPE)
HDPE properties are mainly transparency,water vapor tightness, resistance at low temperatures, and impact resistance dangerous products. It is used in the preparation of food packaging, detergents, automotive oils,shampoo, fish boxes, containers painting, among others.

Polyvinyl chloride (PVC or V)
PVC is one of the plastic materials that provides greater variability for both the manufacture of packaging rigid and flexible.

Its properties are: resistance
mechanical transparency but also can be colored, aroma tightness, gas and steam water as well as oil and grease resistance.

It is used in the production of containers for oils, juices, dressings, shampoo, and jugs of purified water. Also in the manufacture of drug blisters, batteries, toys and treats.

Low density polyethylene (LDPE / LDPE):
LDPE is versatility. Its transparency, flexibility, strength and economy make is present in a variety of containers, alone or in combination with other materials, and various bags for different applications such as shops, for frozen products, and products Industrial.
Furthermore, with LDPE density produced food packaging films and industrial products (milk, water, etc.)


Lightweight and unbreakable

Flexibility and mechanical resistance

Versatility of shapes (softens at high-temp and is embrittled to low-temp

May occupy storage space
when it is a finished package
(rigid containers)

Some are gas permeable,
aromas and water vapor

How Biodegradable Plastic is made?
The Biodegradables Plastics are made of organic materials derived from renewable sources such as potato starch, which at the end of its life, to be removed as organic residue, this is decomposed in a short period of time, in the presence of microorganisms serving organic fertilizer for plants.

Main Types
Biodegradable polymers can be classified as follows:

Polymers extracted or removed directly from biomass: polysaccharides such as starch and cellulose. Proteins such as casein, keratin and collagen.

Polymers produced by classical chemical synthesis using renewable biological monomers.

Polymers produced by microorganisms, producing bacteria native to the genetically modified.
Main Uses
Its used mainly to pack products, and other uses for example the biodegradable bags are used to bring products and then the persons throw the trash in these bags
The bottles are used to containing the contents in perfect condition.

Lower Cost
Protect the environment
Easy to use
Good insulation properties
Multiple use
Are not Toxic
Easy and Fast Production
Withstand high temperatures

The biodegradable plastic haven't a lot of disadvantages but one of they could be the large quantity of water that is used to process the plastic.

Bubble Wrap Corner Protector
The bubble corner protector is manufactured on perforated rolls and is constructed of high tensile strength, triple-layer bubble material that offers superior resistance to tears and punctures while providing maximum surface protection and product cushioning.

Main Uses
Bubble corner protectors are perfect for frames, prints, mirrors and panels during transportation. A heavy-duty 3rd web bubble offers maximum protection. Bubble wrap corners are perforated for easy dispensing

Toxic waste

Environmental problems

Storage difficulties

Flammable hazards

Provides excellent corner protection for any product that has a corner.
Protect frames, desk edges, windows, doors, signs and more.
Bubble protective corners are perforated on a roll for quick dispensing.
Frame protectors are made from heavy duty bubble cushioning.
Bubble cushioning is made from LLDPE resins providing higher puncture resistance, exceptional elongation and tensile strength.
