Polythene Sheets & Liners
Polythene Sheet Pallet Covers protect materials from climatic extremities by providing them with cover. They are available in multiple unique designs that have different functions associated with them.
Some types include :
- Gusseted polythene pallet covers
- Side welded flat pallet covers
- Box-shaped pallet covers or Block Bottom Pallet Covers
- Flat or centre-folded sheet pallet covers
- Short pallet hoods, also known as pallet caps.
Items 1 -3 normally cover the pallet in full. Items 3 & 4 are normally used in combination with pallet wrap
Pallet covers in their many forms are commonly used to protect the goods stacked on the pallet from wind, dirt and rain. Other options include masking the product underneath from UV light or for security reasons to prevent people from seeing what is stacked on the pallet. Pallet covers are a quicker cheaper solution to stretch wrap. If not using a shrink pallet cover, it may be useful to look at our pallet stretch bands.
UV Stable Pallet Covers
UV Stable Pallet Polythene Sheet Covers are another type of Pallet covers that come with an added feature of protecting the cover from Ultra-Violent rays from the sun. This additive incentive helps the pallet cover maintain its original and required form. It also prevents any shift in the strength of the cover that tends to go fragile and brittle in the presence of sunlight. This extends the lifetime of the cover which consequently leads to more durable protection of the material. In cases of shipment of any material to different climatic conditions, the UVI can help preserve the cover during the shipment process.
Pallet Base Poly Sheets
Pallet Base Sheets are used as a base for products’ protection while shipping. They provide the same services as pallet covers i.e. protection from moisture, dust, water and any harmful material, but specifically for the base of the product. The sheets are used when stacking products for shipping. The sheets can be paced down the product and in between the layers to prevent possible harm to the product through contact. Furthermore, they also offer protection from the container and in some cases, provide protection to the container as well. They also exponentially increase the stability of the product while shipment.
Polythene Sheet Skip Liners are used to protect the material inside the skip and the skip itself from the product sometimes as well. The primary concern is that the skip remains intact and clean from the product. A pertinent example would be trash bins and skips. The trash might contain a lot of corrosive and harmful material, skip liners protect the container and can be disposed of later on. Skip liners are available mostly for all sizes of skips. These skips can also be used with ropes for hanging purposed making them space efficient as well. In general, skips are highly efficient for keeping disposed of material.
Euro Slot Bags
These bags get their name from the special shape made designed on them for holding purposes called euro slot. Euro Slot Bags are super clear, highly efficient and high-quality bags. These bags are made up of 40-micron polyethene with some additional features based on the requirements. These bags are used mostly to display items at the point of sale. Small and lightweight items are placed in these bags and displayed in stores usually near reception/checkout. These bags are available in multiple sizes best for holding items like gift cards, USB, sweets, hardware, car parts and different cell phone parts etc.
In order to remove the problems caused by plastic bags, compostable bags were introduced. Compostable Bags are made up of cellulose. Compostable is often misunderstood as biodegradable, biodegradable means that something can be decomposed by bacteria whereas Compostable means that something can be decomposed by bacteria under specific conditions. Upon decomposition, compostable bags produce carbon dioxide, water, and inorganic compounds that are non-toxic. With the ability to decompose they share the same strength as non-recyclable plastic bags. Hence these can be used in places where non-recyclable bags are used. Since they produce nontoxic materials upon decomposition, this makes environmentalists prefer this over plastic bags.
Toner bags are made up of aluminium foil usually 0.016mm thick. For printing purposes, outer layer consists of a plastic sheet. As the name suggests, it is used as a toner container. Toner Bags are also widely used for food packing purposes. Aluminum acts as a barrier to light and oxygen, moisture, germs, and odours which helps in keeping the food safe for a more extended period. Above mentioned properties make it suitable for pharmaceutical packaging. Food and pharmaceutical industry are critical clients of Toner Bags industry since both of them are related to human health it is essential that the packaging is excellently produced to prevent any major loss to the product which might produce fatal results.
Handle carrier bags
Handle carrier bags are simple carrier bags but with a simple; yet, a massive utility addition i.e. a rope or a certain handle made explicitly to cater to holding purposes. The addition increases the utility of the bag which helps people use it more often in daily life more than the original carrier bag. It is used for shopping, transporting and in some cases storage purposes as well. However, the disadvantage, i.e., not eco-friendly which existed in carrier bags transcends to this product as well. This does not stop the product from being the most widely used carrier bag worldwide; however, steps are being taken to reduce this through recycling.
Plastic Carrier Bags
Carrier bags are made up of plastic, paper or sometimes fabric as well. Carrier bags are primarily used for carrying around things easily and efficiently. Plastic bags are the ones mostly used. Plastic bags do not biodegrade instead they break down into smaller bits. Like any plastic product they should always be recycled wherever possible after use.
Tote liners are made from Prime Virgin FDA resins. Tote liners are mostly used to protect the product and container at the same time, it helps in protecting the container from harming materials stored in it for transporting, storing or processing purposes. These are designed such that they cover sides and bottom of the container. One can say that tote liner is heavy duty, protective polyethylene plastic bag. There are different grades of liners available in the market. Food grade liners are safe to put food in them. Some polythene sheet grades are used for holding chemicals only. They are widely used in the packaging of chemicals, food, pharmaceutical products, adhesives, coatings etc.
Mailer Envelopes are used for sending letters, literature, i.e., books, multimedia (CD’s, tapes and other packages). Envelops used for letters are mostly made up of thick paper, for ages wax seals were used for sealing, but nowadays self-seal envelops are available in the market. For different kinds of packages, different envelopes are designed keeping in focus their shape and safety. Bubble envelopes are designed especially for the safety purposes; they help in delivering fragile objects without being broken. Envelops mostly contain sender and recipient addresses and contact information which helps in transferring the packages from one place to another through post method.
Polythene sheets are supplied as loose cut or wound on rolls and can be configured as flat, single or double layer format, centre-folded or multi-folded. The configuration is normally determined by customer requirement and preference or dictated by the width required. For example, it doesn’t matter if lower thickness products are folded, as the crease will easily be removed whereas thicker sheets may not want to be folded as it will be near impossible to remove the crease. For very wide format poly sheets it may not be possible to get the width you require without folding at the source.
There are other factors to take into account such as slip, clarity, colour as well as performance enhancing additives. Top sheets may be required in an opaque colour or with UVI additive. These options would help prevent the sun’s rays from penetrating the cover and harming what is beneath or breaking the sheet down rendering it useless over time. A base sheet may need to be low slip to prevent product slipping once stacked on top. If you are wrapping an item in a polythene sheet, you may want it treated so that adhesive tapes stick to it and don’t easily peel away, or you may want to write on the sheet with a marker. If you don’t treat the sheet first, the tape will not stick, and the marker may rub off easily after a lengthy period of time. You may want a high clarity sheet so that your product is not masked; this is a common request when wrapping point of sale items. Sheets may also have a high gloss appearance.
In the construction industry, polythene sheeting is used as a vapour barrier which restricts the moisture flow within the walls, which can weaken the structure of walls. They are also used in window films, flooring and roofing. Polythene sheet is used to prevent the ocean from being contaminated during ship building projects. The key to using the correct configuration is our understanding of your application.
Embossed sacks and bags are produced with an embossed layer, to help prevent the sacks from slipping when stacked together. Whilst the bags are being converted, small strips of polythene sheet is heated and minute embossed pockets are forced outwards away from the surface of the material. This creates a raised dimple on the surface of the sacks, and when applied in their thousands across the width of the material, it creates an embossed effect. This method has proved to be more successful than ordinary surface slip and COF methods and is cheaper than spraying a coating onto the layers of sacks when stacked on the pallet. It is cheaper to produce bags this way and is food safe as it does not require additional materials or coating to work. Strips are applied down the length of the sacks so that when you change the direction of the sacks when brick stacked on pallets, the embossed strips meet and still prove effective, regardless of how they are stacked and what direction they are laid.
Shrink Pallet Covers are mainly used to secure a load to a pallet by shrink wrapping. With thicker grades of material, it is possible to use an industrial shrink gun to heat the cover when fitted. Heat shrink polythene sheet is stretched and blown as a bubble when it is being made. It is then cooled and wound onto a roll this way. Heating the shrink pallet cover with a shrink gun then returns it to its original pre-stretched molecular structure, securing the load in the process.
Valve sacks are made up of paper, extruded plastic or polypropylene. These bags are used for high-speed filling purposes. These are best for storing powdered like cement and granular like sugar substances. Valve is closed after filling the bag, this is a lot faster and simple than sewing. Valves can be internal valves, external valves or heat sealed valves. Paper and propylene sacks are mostly used for powdered products like cement, food products etc., whereas Polypropylene sacks are used for heavy-duty purposes. Polypropylene sacks are not best suitable for powdered substances but they can be made useful by using liners.
