How to choose the most suitable packaging solution for your food items

 

To get a most suitable packaging solution for your lovely item, you have to consider several points to make it perfect. Upon my knowledge and experience, basically you shall take these factors into your consideration.

1) Tensile strength

Tensile strength is the basis of whole bag strength, and this is also the first factor we shall consider. Other factors, such as heat sealing, pressure resistant ability, fall off ability, anti penetrate ability also have some relative with it. Tensile strength is up to the materials you choose for your packaging solution. CPP, BOPP, PET, PE, PVC, Nylon, Al, Paper, PVA, lamination film, etc, different tensile strength has to be carefully considered.

2) Elongation rate

Elongation rate is similar as tensile strength, is our consideration. When the packaging bag suffers outside impact, fall off, etc, whether the bag will break, elongation rate has influence on the possibility. Usually speaking, high elongation rate cause less possibility of bag breakage.

3) Tear Strength

Tear strength is the stress on the cross section of film, working as a resistance for the initial tear force.

4) Peel strength:

For lamination film, peel strength is essential consideration. Some items may require low peel strength, that will be convenient for consumers to use. Some items may require high bond strength to well protect the inside content. We will achieve based on your particular situation.

5) Heat sealing strength

Film has to be sealed together into packaging bag, holding inside contents. Some items require high sealing strength to enhance holding ability, especially liquid items such as water, milk. There shall absolutely be no leakage. Some require low sealing strength, for consumers’ easy use, for example, packaging for ice cream, frozen sucker. We will provide you best sealing performance for your item, best packaging solution.

6) Stiffness

Fine stiffness is essential when you want to realize excellent presentation effects on goods shelf. Sometimes you would like to your packaging film or bag to be certain kind of shape for promotion, stiffness has to be seriously considered. Some time, we have to apply rigid PET film, PVC film or other film to realize shape effects.

7) Barrier performance

To well protect the food, barrier performance has to be carefully considered. Some products require highest barrier performance, and some products may require lower barrier performance, the best is the most suitable for the products. There are mainly four types of barrier materials: metallized film, PVDC coated film, Al foil, Nylon film with performance different from each other.

8) Fall off ability

During transportation, fall off may sometimes occur, to avoid breakage or damage for the inside content, certain falling off ability is required.

9) Pressure resistant ability

Fine pressure resistant film will well protect the inside content.

10) Oil resistant ability

For oily food items, this is to be one of the key considerations.

11) Low temperature resistance

Often, the products has to fight against low temperature, such as cold storage, winter cold days, that also impose certain requirements for the packaging materials. To deal with these cold environments, most suitable materials has to be seriously decided.

12) High temperature resistance

Some items need to be put into microwave oven, some may be required to be boiled, these all require the film, ink, glue raw material to resist some high temperature.

13) Coefficient of friction

Coefficient of friction has great influence on the opening ability, suitability of the film for the auto packaging machine and the speed of packaging, etc. When we choose a packaging film for the autopackaging machine, there shall be more things to consider. As the performance of the film has to be matched with the packaging machine. We would like much to talk with you about your packaging machine, so most suitable packaging film to be decided.

14) Air-tight ability

Some food items may require to be well protected against air, as the oxygen or water in the air may cause the food go bad. For example, when you pack biscuits, you have to fight against moisture. Some items may require vacuum packaging.

15) Easy open ability

Easy open ability is important when you want your items to be easily used by the consumers. Do you ever encounter a problem that when you bought your lovely food home, however you take a lot of effort to get it out of the bag? Try to be easy use, this is what each manufacturer shall do.

16) Easy to bring about

You want your foods to be everywhere with your consumers. When they go outside, yeah, they have your items in their travelling bag. This is also to bring ease and convenience to your consumers. I love travelling outside, and I pay much attention to the items easy to bring with me. I would like to share with you my experiences.

17) Presentation effects 

Ok, your food is put on goods shelf in the super market now, then what is important, eye-catching, right? There are many food items from many other food producers, how do you achieve catching the consumers’ eyes at the first moment when they wander around in front of goods shelf? Presentation effects shall surely be taken into your consideration when you choose a packaging film. Think about it, what’s the best presentation effects for your food?

18) Light shading

Some food has to be well protected against sunlight, such as cheese, coffee, they need fine light shading. This is very easy to achieve, you can choose paper, or aluminum or metalized film to get great performance. What I emphasize is that you get the item at the lowest cost.

19) Fragrance protect

This is absolutely necessary for food items, and this is also achieve when great air-tight performance is achieved.

20) Hand feeling

Hand feeling is very important for product promoting, as when a consumer picks up your food product in hand, maybe at that moment, they forms an intuitional understanding of your products, and this may have some influence on their decision whether they will buy your products. Different materials bear different hand feelings, especially with different thickness and different lamination, they provide so many kinds of unspeakable feelings that influence the profile of your product in their eyes. We welcome you to talk about your choice for your product packaging, for your final decision.

21) Anti-fake ability

Another point, you need to protect your patent, your plant name, and your rights on your food items. Laser holographic or hot stamping foils has to be applied. I am providing you high quality products and services.

22) Cost effective

Finally, we come to cost. Our principle is to provide the best solution for our customers at the lowest cost. This is what we are good at.

Nice color is acceptable. Reverse printing on the film, high adhesive of ink on the film.

Process of laminating:

Laminating is achieved by applying a layer of glue between two kinds of film and making them into one integration. Also we can achieve combination by co-extrusion, this is upon your requirements.
