Our Products

At DJW, we offer a variety of products and services to meet your needs. We currently offer the following range of products:

Lidding Films

We offer advance lidding films for packaging applications, offering innovative and economical solutions for food packaging. Lidding films are widely popular in the industry and are typically used as closure on ready meals, aluminium foil trays, plastic bowls or various containers such as yoghurt, soup, meat and cheese pots thanks to their peelable, temperature resistant and Anti-Fog characteristics. Attractive and Resilient, we offer these films with different properties from thickness to sealing substrates so that in whatever case, there is the right film for you. Lidding films are provided coextruded or laminated for printing purposes.

We offer a wide range of Lidding properties to meet your requirements:

  • High clarity peal steal to Aluminium and are suitable for printing
  • Low, Medium and High Barrier
  • Weld, Peal Burst
  • Variety of Thickness
  • Various Sealing substrates

BOPP

Biaxially Oriented Polypropylene (BOPP) is one of the most favoured packaging across the industries spectrum, and the film appropriate for the food packaging industry is co-extruded and heat sealable. BOPP is cost effective thanks to its higher surface area per unit weight and has a much lower moisture transmission rate than equivalent products. A combination of excellent slip and optical properties, with BOPPs inert nature and tensile strength makes it perfect for food and beverage packaging especially relating to drinks and confectionery. We can offer BOPP with different:

  • Variety of Thickness
  • Various Seal Types

Polyesters

Our polyester products can be used in a wide range of applications, and ensure that food looks safe, fresh, appealing and that the packaging is proportionate. The PET range offers high tensile strength and thermal stability which makes these products popular with customers involved in the sale of Ovenable and microwaveable packaging. Its resistance to water, high strength to weight ratio and availability as a recyclable and economic plastic makes it a highly popular and convenient choice.

Our ranges offer a:

  • A Variety of Thickness
  • Various Seal Types
  • Various Coatings

Environmentally Friendly Products

We offer a range of environmentally products offering customers a feasible and viable choice as an alternative to conventional films. These are an excellent choice for customers seeking biodegradable and compostable options. We offer;

  • Degradable and compostable Produce Film
  • A more recyclable alternative to BOPP
  • Polyolefin Shrink Film – ‘I Am Green’ Certification
  • 100% preformed Mono PET tray and PET HB Lidding films - Click Here to Download

Our Commitment to the Environment

As an individual firm we take an active role in our commitment to the environment as a wider part of industry initiative. We recognise the need to reduce the wastage of packaging and move towards degradable and recyclable films, hence our recent introduction of the Green Films Range offering an alternative product for customers.

We have a collective responsibility to minimize our carbon footprint and therefore we ensure the greenest mode of production and distribution is used in our supply chain. In distribution, for example, we choose Shipping as our preferred method over air freight, which saves up to 77% in CO2e (kg)*. We always ensure our suppliers are environmentally responsible and where possible opt to employ eco-friendly measures.

We are passionate about the environment, going beyond regulation. Collectively we can make food packaging more sustainable, and DJW Packaging is taking a leading role and the forefront of environmental responsibility.

Blown Film Extrusion

The manufacture of plastic film for products such as shopping bags and continuous sheeting is achieved using a blown film line. This process is the same as a regular extrusion process up until the die. There are three main types of dies used in this process: annular (or crosshead), spider, and spiral. Annular dies are the simplest and rely on the polymer melt channelling around the entire cross section of the die before exiting the die; this can result in uneven flow. Spider dies consist of a central mandrel attached to the outer die ring via a number of "legs"; while flow is more symmetrical than in annular dies, a number of weld lines are produced which weaken the film. Spiral dies remove the issue of weld lines and asymmetrical flow but are by far the most complex.

The melt is cooled somewhat before leaving the die to yield a weak semi-solid tube. This tube's diameter is rapidly expanded via air pressure, and the tube is drawn upwards with rollers, stretching the plastic in both the transverse and draw directions. The drawing and blowing cause the film to be thinner than the extruded tube, and also preferentially aligns the polymer molecular chains in the direction that sees the most plastic strain. If the film is drawn more than it is blown (the final tube diameter is close to the extruded diameter) the polymer molecules will be highly aligned with the draw direction, making a film that is strong in that direction, but weak in the transverse direction. A film that has significantly larger diameter than the extruded diameter will have more strength in the transverse direction, but less in the draw direction.

In the case of polyethylene and other semi-crystalline polymers, as the film cools it crystallizes at what is known as the frost line. As the film continues to cool, it is drawn through several sets of nip rollers to flatten it into lay-flat tubing, which can then be spooled or slit into two or more rolls of sheeting.

Sheet/Film Extrusion

Sheet/film extrusion is used to extrude plastic sheets or films that are too thick to be blown. There are two types of dies used: T-shaped and Coat Hanger. The purpose of these dies is to reorient and guide the flow of polymer melt from a single round output from the extruder to a thin, flat planar flow. In both die types ensure constant, uniform flow across the entire cross-sectional area of the die. Cooling is typically by pulling through a set of cooling rolls (calendar or "chill" rolls). In sheet extrusion, these rolls not only deliver the necessary cooling but also determine sheet thickness and surface texture. Often co-extrusion is used to apply one or more layers on top of a base material to obtain specific properties such as UV-absorption, texture, oxygen permeation resistance, or energy reflection.

A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic) and formed via a mould into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mould which can vary in depths from 1 to 36 inches typically) is highly important and greatly affects forming cycle times for most plastics.
