The stand-up doypack pouches and also, the flat bottom and side gusseted bags are made from high performance multilayer materials such as: PET, PE, OPP, CPP, EVOH and more.
For more information, see below the list of necessary explanations.
CPP film has the characteristics of good transparency, high gloss, good rigidity, good moisture resistance, and excellent heat resistance and easy sealing.
CPP film is suitable for food packaging and candy packaging (twisted film), as well as pharmaceutical packaging as well as pouches and adhesive tape.
CPP has excellent heat resistance and combined with excellent acid, alkali and grease resistance, it becomes the first choice for bread product packaging or laminate materials. It is safe in contact with food, has excellent performance, does not affect the taste of food.
A rigid, high clarity film which is combined with other films, (such as LDPE) for heat sealing. It can also be coated with some other material or plated for greatly improved barrier properties.
OPP is mainly used in beverage and detergent labeling. The advantages are high transparency, good gloss and high shrinkage.
The shampoo, shower gel, detergent labels that need to be moisture resistant are made of OPP and have the advantages of transparency, high strength, moisture resistance and drop resistance .
Polyethylene (PE) is the most common plastic.
Its main use is in packaging (plastic bags, plastic films, geomembranes, in containers such as bottles).
Polyethylene is a thermoplastic polymer composed of long hydrocarbon chains. For common commercial grades the melting point is typically in the 105 to 180°C range.
It is processable by blowing, injection, extrusion and suitable for the production of films, sheets. It has transparency and gloss and excellent mechanical properties as well as gas or perfume barrierproperties.
It has excellent chemical resistance, and is not attacked by strong acids or bases. It also resists mild oxidants and reductants.
PET is the most recycled plastic in the world.
The heat-resistant PET protective film has the characteristics of excellent heat resistance, chemical resistance, as well as non-stick properties and non-flammable capabilities.
These elements make it suitable for thermal adhesion (thermal insulation) and adhesion (surface treated on one side) at the same time.
The MET-PET film is a polyester film coated with aluminum powder.
Polyethylene terephthalate (PET) films are heat resistant with very good oxygen barrier properties. When PET films are laminated with metal foil (MET-PET), their oxygen-water barrier is increased film and UV radiation is blocked.
Metal films for flexible packaging are necessary when the product requires extra protection to ensure a longer shelf life. MET-PET films provide protective properties for foods that require limited visibility.
It is a suitable film for packages of food sensitive to moisture or oxidation, such as coffee or instant soups.
High quality single-sided OPP lamination films suitable for offset printing as well as digital printing.
The excellent ink adhesion to the treated surface and the very uniform, low gloss surface are some of the advantages of MAT-OPP.
It is used in confectionery and bakery packaging, dairy products, biscuits and crisps - snacks.
The matte OPP 'Soft Touch' film is designed for high quality lamination.
It has unique soft touch properties with excellent scratch resistance. Coated with more aggressive adhesive for better finish and bonding for digital output.
High quality single sided "Soft Touch" digital laminating films are suitable for offset printing and digital production.
The PP polypropylene film is suitable for food contact and is used to package a wide range of products.
This film is available in different thicknesses and qualities depending on the application. These films can be printed or perforated.
It has a much higher melting point, so better temperature resistance than PE.
Two types of PP films are used in packaging, CPP and OPP.
PP can be metallized resulting in improved gas barrier properties for demanding applications where long product life is important.
Unlike paper and other cellulose products,PP is not biodegradable but its waste does not produce toxic or harmful by-products.
Ethylene-vinyl alcohol copolymer (EVOH) is used in plastic films to improve oxygen barrier properties.
It is a flexible, crystalline and glossy thermoplastic copolymer with excellent resistance to flexural cracking and very high resistance to hydrocarbons, oils and organic solvents and also has some of the best gas barrier properties such as oxygen, nitrogen and carbon dioxide, making it particularly suitable for packaging food, medicine, cosmetics and other perishable or sensitive products to extend shelf life.
EVOH waste produces no toxic or harmful by-products when properly incinerated.
EVOH film is often used for fresh produce when minimal permeability is required as well as for medical and pharmaceutical packaging as well as agricultural films.
