Tea product is very sensitive for the loss of aroma quality while it is stored in the unpleasant condition. Therefore, the appropriate the packaging material is the most concerned in order to keep the quality of the product. Moreover, packaging is used to prolong the shelf-life. This task provides the description of the packing including primary, secondary and tertiary packaging and outline the chosen system meets the shelf-life requirements
 * Packaging that meet food quality and safety requirements**

FINAL EDITING:

The objective: is to protect the tea contents in the bag as it goes from the factory till the hands of the consumer, against any deteriorating influences. It is to provide a suitable packaging to the product that is appealing to the eye of the purchaser and also facilitate good handling of the product. The tea flavour is highly sensitive and unstable as it vaporizes by itself and re-oxidizes to bring about an undesirable flavour change. Tea has a tendency to absorb moisture thus harming the quality. Light, oxygen and higher temperatures are other factors, which affect the quality of the tea and hence the shelf life of the tea is relatively much lesser than the other dried products. The changes in food packaging in particular are remarkable due to the development of packaging material and machines used in the recent times. Some of the materials used for packaging are cellophane paper, polyethylene, polypropylene, polyvinylidene chloride, vinylon and aluminium foils. Each of the above-mentioned have merits and demerits thus by using them in the laminated forms, their combinations can complement each other. Therefore, an appropriate packaging system is of prime importance to retain the quality of the manufactured product. Use of adequate packaging materials and the suitable systems have known to extend the shelf life. This task provides the description of the packing that includes the primary, secondary and tertiary packaging and the outlines the chosen systems, which meets the shelf-life requirements. The ground brown rice and red beans have a longer shelf life due to its roasting (heat treatment). The best storage conditions for saving the quality of cereal tea (after packaging) is by keeping in dark and lowering the temperature, humidity and oxygen level.

This tea bag is small sealed bag, which contains green tea leaves, brown rice and red beans. Once the tea has been brewed, it makes it easier to dispose the tealeaves, cereals and pulses. It performs the same function as a tea infuser. The infusion sachets containing the tea ingredients are produced from either ‘heat seal’ or ‘non heat seal’ fibrous porous web material. The heat seal paper generally comprises of 2 layers the filtration layer and the sealing layer. The sealing layer includes the feasible polymeric fibres that would allow the 2 layers of the paper to be sealed in the production of infusion bags, while the other layer acts as an insulating layer to prevent the polymer sticking to the other material. 1st layer: comprises mainly of the vegetable fibres 2nd layer: comprises mainly of the hardwood fibres 1st layer accounts for about 50-70% of the web material weight. The fibres generally have the length of 0.8mm to 0.9mm. Apart from the use of vegetable fibres we can also use sisal, jute or softwood. For the 2nd layer it accounts for 20-40% of the web material weight. The hard wood fibres would generally have 0.25mm to 2.5mm in length. The width is approximately 10 to 25 microns. The fibres of the 2nd layer, which are chosen, are finer and shorter than the 1st layer i.e. this layer has shorter pores. This plays a significant role as it provides a good pattern definition, lower cohesiveness and greater ease of movement when compared to the longer fibres of the 1st layer. The tea bags are attached with a piece of string along with a paper label at the top (may contain the company logo or design). This assists in removing the bag after infusion and also in identifying the brand. Tea bag filter – The widely used material for tea bag is filter paper, silk or porous paper. The tea bag is heat sealed after the ingredients are placed. They usually have heat sealable thermoplastics (polypropylene or pvc) on the inner side of the tea bag surface.

A single flower bag contains 2 chrysanthemum flowers (weighed approximately 0.4g) the materials used for the bag aids in preserving the nature of the dried flower; the bag is sealed by thermo-sealable plastic. Clear medium duty polythene bag is used to pack the flower and seal thermal sealing machine.

In order to extend the product shelf life and to trap the spread of aroma, the tea bag and the chrysanthemum flower pack is sealed into an aluminium sachet. For the material used in the secondary packaging, there are three layers of the sachet. The first layer is OPP layer that is used to be a container of the tea bag. OPP, oriented polypropylene, is a flexible material derived from melting and orienting (stretching!) a polymer called polypropylene. OPP films are very versatile, can be adapted for many diverse uses and are suitable for many types of packaging machines. Because of their physical and barrier properties especially when coated - OPP films are used in labelling and packaging for a large range of consumer products such as biscuits, snack foods, confectionery, bakery goods, soft drinks, aerosol cans and overwrap applications. The aluminium foil and MPET were considered to be second layer due to the ability of product extending shelf life and the cost. The MPET is suitable to retain the 6-12 months shelf-life. The last layer that is in contact with the tea bag and the flower pack is Linear low-density polyethylene (LLDPE) is a substantially linear polymer (polyethylene). It is very flexible and elongates under stress. It can be used to make thinner films, with better environmental stress cracking resistance. It has good resistance to chemicals and to ultraviolet radiation. It has good electrical properties.

The 20 sachets of tea and 20 packs of Chrysanthemum flower are packed into the carton box, which is labelled with the brand, and nutrition fact, which meet the required packaging standards. The carton box is then sealed by laminated plastic that overwraps the outer carton confirming to the consumer that the product inside has not been touched since it left the factory.
