Types of food packaging

TRAYS AND PUNNETS

Bandeja

Relatively shallow containers that may have a lid. They are used as food containers. There are plastic trays of all kind: those used as a primary food-contact packaging, such as foamed, transparent, high-barrier, peelable and reclosable trays and those used as secondary packages, which are normally thermoformed for containing other food packages.

BAG IN BOX

Bag in box

They are used for storing and transporting liquids. It is formed by an outer packaging, normally made of cardboard and an inner plastic bag. In many cases, the plastic bag incorporates a tap for dosing the product. It is widely used to package wine. 

SINGLE-USE BAGS

Bolsa de un solo uso

Flexible containers, generally closed in all their parts except one, to carry products such as fruits and vegetables. They can be T-shirt type, loop handle type or punched handle type.

REUSABLE BAGS

Bolsas reutilizables

Similar to single-use bags in shape and designed to be reused normally at least 15 times. Their dimensions vary with respect to single-use bags. They are thicker and have higher capacity and higher mechanical resistance.

BOTTLES

Botellas

Rigid containers consisting of a round neck relatively smaller than the body of the bottle and with an opening, where there is a cap to keep the product contained inside. The body section can be round, oval, square, oblong or a combination of them.

JARS

Botes

Rigid containers consisting of a round neck with a diameter similar to that of the body diameter and with a relatively large opening capable of supporting a lid to keep the product inside. The section of the body is usually round or square

BOXES

Cajas

Rigid containers consisting of a base and four sides for storing and transporting fruits and vegetables.

DOY-PACK

Doy-pack

Flexible containers designed so that the base allows them to be held in an upright position both filled and empty. They usually incorporate two side longitudinal welds and another one in the upper part. In many cases, they have a mouthpiece to ration the product, closed with a cap.

PEELABLE PACKAGES

Envase pelable

Packaging consisting of a tub sealed with a film in the upper part, so that the product contained inside is perfectly insulated from the outside environment. A packaging is peelable (also called Easy-peel) when a great stretching force is not required to separate the film lid from the tub.

FILM

Film A continuous and thin layer of plastic material with a small thickness. When the thickness is higher than approximately 250 microns, we do not consider it a film, but a sheet.

STRETCH FILM

Film estirable Type of film that has a good tensile strength and very high stretching percentages. Due to this property, it is mainly used in packaging for grouping small packaging units. It can also be used in other applications such as combined with trays when packing bakery products and fruit.

SHRINK FILM

Film retráctil

Type of film that, when subjected to heat, shrinks in one or two directions (longitudinal and transverse). It is used to protect and immobilise the content, thus being in contact with the product. Some examples are packages for cheese wedges and packs of water.

FLOW-PACK

Flow Pack This packaging is formed by a film that has one longitudinal and two transverse welds and forms a perfectly sealed bag that contains the product.

CANS

Garrafa

Rigid containers consisting of a round neck of smaller diameter than the body and with an opening where there is a cap to keep the product contained inside. They differ from bottles and jars in the greater capacity, as well as in the applications in which they are used. The body section can be round, oval, square, oblong or a combination of them.

 

NETS

Mallas Containers formed by crossed plastic threads creating a regular pattern. They are used to contain products inside, mainly to carry or transport them, since the product is not isolated from the outside environment. They are usually tubular and are closed by two staples.

SLEEVES

Sleeve Tube-like films (sleeves) that contract in the transverse direction when being subjected to heat, thus taking the form of the packaging they cover. They are used as a secondary packaging for hollow bodies, such as bottles and jars, normally for decorative purposes (since it is usually printed) or for grouping products (such as promotional packs).

CAPS AND LIDS

Tapones y tapas Round fittings used for closing bottles, jars or cans, among others, by pressure or threading. In some cases, the function of the cap is just to close the bottle, while in other cases they can ration the content by means of mouthpieces, tap-like caps, etc.

TUBES

Tubos Cylindrical containers with a sealed end and a dispenser in the other end. The dispenser is closed with a cap.
