There are many kinds of vegetables, and the packaging methods are usually different due to different vegetable characteristics and requirements. Each vegetable has its own suitable packaging method. When people buy vegetables, the most important thing is to keep them green and fresh. Here we will introduce the most common and popular packaging methods:
Among all green vegetables, leafy vegetables account for the majority, such as lettuce, spinach, cauliflower, coriander, chives…
They vary in length, so the size of the bag to be packed varies greatly from one to other. In that case, a machine that can automatic detect leafy vegetable length is very important, and could save lots of extra work and downtime for adjust the machine and bag length.
Check leafy vegetable packing machine:
Anti-fog film: anti-fog film is a very wise choice when you choose packing film material, since leafy vegetable will be very easy to raise fog while it stay in closed bag
For long time. Considering the ventilation and breathability, many customers will prefer anti-fog film, and add hole punching device on the flow packing machine to punch holes in the bag. Breathable bags can avoid the leafy vegetables will got rot and then can prolong the preservation period.
The most popular Leafy vegetable packaging machine is model 450X,600X,700X;
The feeding conveyor has equipped with rolling balls to prevents the leaves from being damaged in the process of conveying vegetables, and to reduces the friction between the vegetables and the side wall, thereby to improve the packaging efficiency;
Design of grating electric eye: Considering the leaf vegetables is not regular shape, and with different length, the product sensor is a pair of opposite-beam gratings instead of ordinary single electric sensor, which can improve the sensitivity and accuracy of the machine to better identify vegetables, and then cutting and sealing the bag much accuracy.
Down paper flow packing machine is more suitable for leafy vegetables. The middle sealing mechanism is above the vegetables, when the leafy vegetables enter the bag maker, go through to the middle sealing extend to the end sealing. The film below the wet vegetable can perfect protects the machine to get wet, specially the middle sealing mechanism, effectively prolong its service life;
End-seal with drag chain design: prevent the leaves from being clamped, and ensure that all the vegetables can be packaged, sealed and cut smoothly;
For relatively slender melons and fruits,like loofah, bitter gourd, and cucumber, can also be packed in ordinary anti-fog film bags, In this this case, can use similar machine like leafy vegetable packing machine.
But if it is big round ones like cauliflower, Chinese cabbage, you can consider wrapping by preservative film.
Check Semi-automatic Preservative film packing machine
If your production capacity is not particularly large, it is recommended to consider a semi-automatic preservative film packaging machine, because the price of automatic one will be very high cost, and there are relatively few professional manufacturers currently; Semi-automatic preservative film wrapping machine can ensure lower input costs.
There are also some tiny leafy vegetables, such as bean sprouts, Dutch beans, small peppers, etc., and small sage fruits, etc., Those small vegetables are not able to handle by general leafy vegetable, also not good to do with preservative film.
This type of vegetable can be considered first packed into plastic tray, and then packed into plastic bag. It’ll be more convenient during packing process also easier for end customer to carry and use.
Check small vegetable/fruit with plastic tray and then into bags.
Features for Small vegetable packaging machine with Plastic Tray
Feeding conveyor generally using pusher style conveyor, because the plastic tray is more regular in shape, with a pusher, can effectively assist to speed up conveying process, then can greatly improve the packaging efficiency.
The Flow Packing Machine generally adoptup paper machine, means the packing film will install on above of the main machine, in this way can ensure the longitudinal seal will be at the bottom of the plastic tray, to complete perfect packaging bag effect;.
The answer is no.
If you already check above project video, you already understand “Different vegetables will has different packaging style, it determine the machine design will need to focus on different point. We do not recommend using ONE machine for all vegetables.
If you are starting your business with low budget. We strongly recommend you to choose one of the categories and start trying to open the local market step by step. Later on, you can add vegetable categories and new equipment when your business grows. This will not only reduce the risk of investment, but also make your business professional and simple.
Automatic machines will definitely faster than semi-automatic ones, The level of automation will decide machine speed. It also related to your vegetable features. The one with plastic tray with regular shape, can also run faster.
Most cases, customer would prefer stainless steel as constructing material, no matter for the body frame of the machine. Because it has higher durability and stronger resistance ability against corrosion, wet environment, different temperature, and to withstand other harsh environmental changes.

Food packaging comes in many varieties and types of materials: glass (bottles), plastic containers, cans, boxes, stand-up pouches (flexible packaging) just to name a few.
When discussing food packaging here, I want to discuss stand-up pouches (a layman term I’ve heard often is “food bag” or “food pouch”). The reason for this is that I get a lot of inquiries about this type of flexible packaging, and it is one of the fastest growing forms of packaging in the industry. Stand-up pouches are used primarily for grains and snack foods, but the variety of food types that use stand-up pouches are increasing everyday.
(Bags used for frozen vegetables, for example, which are different than stand-up pouches, are still under the umbrella of “flexible food packaging”.)
When deciding on food packaging there are an exhausting amount of options. Just the variety of films (plastics) used can make a person’s head spin.
But any good manufacturer or packaging sales professional can help you navigate through the all the technical terms and confusing acronyms.
There are things, however, that you can consider ahead of time that will make the process of purchasing food packaging a lot smoother.
Does your product require a long shelf-life? Of course everyone would want their product to have the longest shelf-life possible, but it’s important to have an idea of the minimum amount of shelf-life that you require. The reason for knowing this is because longer shelf-life = stronger barrier protection = higher cost for the packaging.
Barrier protection is concerned primarily with oxygen and moisture (water). These two are the biggest culprits involved in food spoilage, so keeping oxygen and moisture out of your food packaging is extremely important for improving the longevity of your food product.
“Transmission Rates” are the rates at which the packaging industry measure the amount of oxygen and moisture that pass through the packaging in a 24 hour period (usually in grams or cc, per 100 square inches per 24 hours).
WVTR – Water Vapor Transmission Rate or MVTR – Moisture Vapor Transmission Rate
OTR – Oxygen Transmission Rate
Barrier protection can be determined by multiple factors:
Also, oxygen can be purged from the packaging using nitrogen before sealing to help lengthen shelf-life. Of course this is done during product fulfillment and has nothing to do with the manufacturing.
** Note: Thickness of film is measured in mils. These are 1/th of an inch. Don’t confuse “mil” with millimeter (mm) (Outside the U.S., Microns(μ) are used as a measurement)
When someone asks me for a food bag or stand-up pouch, my first question is “what does it look like”. If you do a google search for “food bag packaging” you’ll get a variety of different types and styles, colors and shapes. This is often a good start for people who are not entirely sure what they want.
The style and size of food packaging determines not only the aesthetics, but also the functionality of the packaging. For example, if your product is heavy or very light in weight, there are certain styles that will better suit your packaging needs.
Take note at what bag styles your competitors are using. It is often a good idea to follow suit, as they have already done their research as to the best functional and cost effective packaging solutions to use. But, if you have an ingenious idea for a style that will differentiate your product in a positive way, then pursue that course. If it is truly a great idea, your competitors will likely follow your lead.
Volume, volume, volume. When buying packaging it is almost always the same – the more you buy, the cheaper it gets. It’s that simple.
The nice thing about flexible food packaging ( i.e. stand-up pouches, food bags etc.) is that, when empty, they use very little space and are considerably light-weight. That means that storage and transportation costs can be relatively inexpensive which makes buying in larger quantities that much more appealing.
It’s interesting to note that a manufacturer’s minimum volume requirement (how few bags they are willing to make for you) is determined by the size of your bag. This is because a manufacturer wants you to purchase the entire roll of film that they have to purchase from their raw material supplier. They will then let you know how many bags it will take to use up this roll of film.
A growing trend (in order to stay competitive) is that manufacturers are starting to require that you only need to use half a roll of film, which reduces your minimum volume requirement.
But of course bear in mind that a minimum volume requirement is simply that, “minimum”. So if you are will to buy more than the minimum the price per unit that you pay will be less.
Print quality will affect two things: the appearance of the product on store shelves, and the cost. What is your competitor’s print quality like? How expensive is your product to produce? What is its retail value?
There are two main types of printing on flexible packaging: flexographic (flexo) and rotogravure (gravure).
Flexo is an older technology. The colors are less vibrant than rotogravure. Rotogravure can print high-detailed fine lines and gradients, is typically more expensive and has longer lead times (the time it takes for the packaging to be manufactured and delivered to you).
Rule of thumb:
Flexo = cheaper, average quality, quicker lead times
Rotogravure = more expensive, high quality, longer lead times
Not all manufacturers offer both types of printing.
