Packed lunch containers
What would typically be in a small childs lunch box?
Important topics to revise:
The difference between ergonomics and anthropometrics.
The difference between sustainability, recyclable and renewable.
Materials, in particular, papers, board and card.
Production methods in particular: Batch production.
Practice designing a disposable and reusable lunch box.
These can be reusable or disposable.
Characters, simple shapes and bold bright colours would be used to attract the small child to the food to make it look exciting and fun to eat.
Appealing to a small child:
Bright colours, simple shape, cartoons.
Could your design have a dual purpose? Two functions? Eg, educational facts? Chalk board? Puzzles included etc?
Does this information appeal to the parent/carer or the child? Why is it needed?
Food packaging materials: Card/Paper/Board
Wax coated paper: Waxes are used to make wax paper this coats the paper and card to waterproof it or make it resistant to staining, or to modify its surface properties. For example this would prevent card from getting soggy from a sandwich.
White board is used for packaging because its hygienic, printable, and has a satin finish which makes the product look clean which is important when packaging food.
Window to see the sandwich, made from corn starch. This allows the customer to see the product and it also makes the product look more expensive and attractive.
Disposable packaging creates a lot of waste. Why is it important that these logos are used on the packaging?

2. A typical batch produced product.
Useful websites:
Anthropometrics is the study of the sizes of people in relation to products. For example, chairs used in schools need to be suitable for the average size of pupils in the schools. A small child has small fingers, would they struggle opening a clasp on a packed lunch box? Anthropometric data is used to help design products
Ergonomics is the relationship between people and the products which they use. Is it comfortable? Will it create health problems in later life?
A typical batch produced product.
Batch production is when a small quantity of identical products are made. Batch production may also be labour intensive, but jigs and templates are used to aid production. Batches of the product can be made as often as required. The machines can be easily changed to produce a batch of a different product.
Everyone has a different role which they repeat on every product to make a batch.
Sustainable energy is the sustainable provision of energy that meets the needs of the present without compromising the ability of future generations
Recycling is a process using materials (waste) into new products to prevent waste of potentially useful materials
A renewable resource is a natural resource which can replenish with the passage of time, either through biological reproduction or other naturally recurring processes

3. Important logos on packed lunch containers.
Polypropylene recycling symbol, indicates that this type of plastic can be recycled.
Healthy eating symbols, ‘pressed into the polypropylene casing. Symbol ‘A’ is promotes foods related to a healthy heart. Symbol ’B’ relates to eating fruit and vegetables
Manufactured from a food safe material, polypropylene (PP). Free from chemicals such as BPA, PVC and Phthalates. Injection moulded. Clips hold the lid tightly shut and contents sealed in. Secure food storage. Handle for carrying the container. Drop resistant, relatively unbreakable. Three part construction (two lids/sides and body/casing), allows easy access. Has three integrated divides, for separating different foods. Embossed lid, simple logo/symbol. Recycling and Healthy Eating symbols

Materials for packed lunch containers.
Material: Polypropylene is a thermoplastic polymer, ideal for the manufacture of reusable containers, such as packed lunch containers. It cis an hygienic material as it can be washed easily and resists stains. It is tough, flexible and durable, withstanding every day drops and knocks. it is supplied in a range of colours. Polypropylene offers good resistance to fatigue.
Material: PET / PETE is a thermosetting polymer and has good physical properties of strength , ductility, stiffness and hardness. PET / PETE is 100% recyclable. It is light weight and can be crushed / compressed, making it easy to transport to recycling plants. Most supermarkets have collection points. It is supplied in a range of colours
PAPER AND CELLULOSE FILM This type of packaging material is easy to print on and can be coated, treated or laminated. Often it is manufactured from renewable materials (recycled paper and pulp). It is easy to handle and lightweight. In addition it can be folded into a variety of shapes by machines or by hand. In general it is used for labels, cartons, boxes and wrappings
Polymers / plastics have a reputation of being environmentally unfriendly. They take years and in some cases centuries to decay. However, plastic bags made from Polylactide (PLA) take only five years to decompose. Containers such as drinking bottles and food containers manufactured from PLA, take slightly longer to decay, as they are manufactured from thinker material. Polylactide is referred to as a ‘bioplastic’ because of its environmentally friendly nature.

4. Screen printing process used on packed lunch containers:
The difference between British Standards and European Standards.
Lithography printing process
1. The printing plate has the image to be printed, in relief, on its surface (the image stands out slightly from the printing plate surface) The printing plate is kept dampened. Ink is applied to the plate but it is repelled from the dampened surfaces which are the non-image areas. 3. As the printing cylinder rotates the ink is transferred to the rubber blanket cylinder.
The European Community sets minimum standards of safety and manufacturing quality, that apply across all member countries of the EEC. Manufacturers working to this ‘lowest’ limit, can display the CE symbol on their products. Minimum standards have been established, that apply to a vast range of products, ranging from toys to motor vehicle components. Manufacturers must ensure, that their products at least meet these minimum standards or risk having them removed from the shelves of retailers throughout Europe.
4. The ink, now on the rubber blanket cylinder, is pressed onto the paper or card as it is pulled through the machine. (The paper is trapped between the blanket cylinder and the impression cylinder - these pull the paper through the machine).
Screen printing process used on packed lunch containers:
Screen printing is a technique, that can be used to add colour paints and inks to a range of materials from card and textiles to polyethylene. The example below, shows how simple shape, cut into a template can be used to transfer paint / ink to a polyethylene lid. Once one colour is dry, a second and third and even more layers of colour can be added, using the same screen printing technique
Products that have a British Standards Institute (BSI) Kite Mark stamped on them, have been checked for safety and quality of manufacture, by the BSI. The Institute carries out strict tests, that have been designed to ensure that the product is safe and has been manufactured to a high standard. The BSI Kite Mark is respected throughout the world. If a product being tested meet British Standards, the manufacturer is issued with a licence, allowing the use of the Kite Mark.
