PET packaging

PET

PET in its natural state is a colorless, semi-crystalline resin. Based on how it is processed, PET can be semi-rigid to rigid, and it is very lightweight. It makes a good gas and fair moisture barrier, as well as a good barrier to alcohol (requires additional "barrier" treatment) and solvents. It is strong and impact-resistant. PET becomes white when exposed to chloroform and also certain other chemicals such as toluene. Biodegradation: At least one species of bacterium in the genus Nocardia can degrade PET with an esterase enzyme. Japanese scientists have isolated a bacterium Ideonella sakaiensis that possesses two enzymes which can break down the PET into smaller pieces that the bacterium can digest.

CPP packaging

CPP

This is a cast film whose raw material is polypropylene and can be used as a single film or as a lamination sealant material. The film is enhanced for impact resistance and heat-sealing strength (135°C or lower) making it suitable for high retort pouch applications and as a lamination sealant material. It is a high impact strength and transparent film with the following characteristics:

 

  • Moderate elasticity.
  • Good heat sealability - Improved low temperature sealing.
  • Excellent machine suitability.
  • Superior moisture-proof properties.
  • Exceptional wear resistance (abrasion resistance)
  • Improved shock resistance.
LDPE packaging

LDPE

This series features a line of high-strength cast film whose raw material is L- LDPE (Line Low Density Polyethylene). There are numerous types and grades available suitable for a range of packaging applications. The film is used in packaging for frozen food, processed marine products, pickles and prepared foods, liquid food (soups and seasonings), refill containers (standing pouches), heavyweight products such as rice.

VMCPP packaging

VMCPP

Metallised films have a reflective silvery surface similar to aluminium foil and is highly flammable. The coating also reduces the permeability of the film to light, water and oxygen. The properties of the film remain, such as higher toughness, the ability to be heat sealed, and a lower density at a lower cost than an aluminium foil. This gives metallised films some advantages over aluminium foil and aluminium foil laminates. It was thought that metallised films would become a replacement for aluminium foil laminates, but current films still cannot match the barrier properties of foil. Some very high barrier metallised films are available using EVOH, but are not yet cost effective against foil laminates.

VMPET packaging

VMPET

VMPET film is short for vacuum metallized polyester film, that is achieved under vacuum conditions to deposit a thin layer of aluminum atoms onto the surface of PET (polyester) film substrate, and finally realize a bright metallic film that is widely used in flexible packaging and standup pouch packages.

Aluminium packaging

AL

Aluminium is used for packaging as it is highly malleable and can be easily converted to thin sheets and can be easily folded, rolled and packed. Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, and so it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.

Kraft Paper packaging

Kraft Paper

Kraft paper or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process. Sack kraft paper, or just sack paper, is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability. Pulp produced by the kraft process is stronger than that made by other pulping processes; acidic sulfite processes degrade cellulose more, leading to weaker fibers, and mechanical pulping processes leave most of the lignin with the fibers, whereas kraft pulping removes most of the lignin present originally in the wood. Low lignin is important to the resulting strength of the paper, as the hydrophobic nature of lignin interferes with the formation of the hydrogen bonds between cellulose (and hemicellulose) in the fibers.

RCPP packaging

RCPP

A retort pouch is constructed from a flexible metal-plastic laminate that is able to withstand the thermal processing used for sterilization. The food is first prepared, either raw or cooked, and then sealed into the retort pouch. The pouch is then heated to 240-250°F (116-121°C) for several minutes under high pressure inside a retort or autoclave machine. The food inside is cooked in a similar way to pressure cooking.

BOPP packaging

BOPP

When polypropylene film is extruded and stretched in both the machine direction and across machine direction it is called biaxially oriented polypropylene. Biaxial orientation increases strength and clarity. BOPP is widely used as a packaging material for packaging products such as snack foods, fresh produce and confectionery. It is easy to coat, print and laminate to give the required appearance and properties for use as a packaging material. This process is normally called converting. It is normally produced in large rolls which are slit on slitting machines into smaller rolls for use on packaging machines.
