Like containers and bottles, a variety of plastic resins can be used to make silage film production. The following is a description of some of the different resins used to make films, a description of the commonly used application, and their properties.

LLDPE/LDPE
These two polyethylene resins have similar properties that make them often talked about as if they belong together. They have good moisture retention, good clarity, strong, fair gas barriers, and highly flexible.
Both of them are also used in similar applications, including shrink wrap, stretch wrap, bakery goods, ice and candy, bags for produce, carton liners, envelope film, boil-in-bags, overwrap, bubble packaging, bags-in-a-box, industrial liners, mattress bags, shipping sacks, liners and trash, textile bags, garment bags, grocery sacks, construction, and agricultural silage film production.
However, they are preferable for different applications because of some differences. For example, LDPE is often chosen for its ease of processing, high gloss, and high clarity. On the other hand, LLDPE is chosen for its heat sealability as well as its impact and tensile strength.
LLDPE tends to be used more frequently in things like shrink wraps, non-food and food packaging, stretch wrap, and trash bags.
HDPE
HDPE can be found in similar applications of LLDPE and LDPE because it is one of the polyethylene families. For example, it is used in box liners and cartons, bakery bags, cake mix and cereal bags, industrial liners, grocery sacks, retail bags, shipping sacks, trash bags, agricultural film, envelope material, and many other packages and product.
Due to its down-gauging properties, it has made it into the film market in recent years. By that, manufacturers can use less material to create a package that can produce the same amount of product. Compared to other polyethylene films, HDPE tends to be stiffer, which is valuable for packaging to maintain the shape. It also has a good moisture barrier and strong puncture resistance.
PP
PP film has the characteristics of excellent moisture barriers, good tensile strength, high gloss, and good clarity. It also desirable in packages that need high temperatures for sterilization since it has a high melting point. It is commonly used in items packagings such as snack foods, sanitary and cheese goods, candy, and bakery products.
It also can be found in tobacco wrap, shrink wrap, diaper coverstock, tape, and sterile wrap used in medical care facilities. PP is often combined with acrylic or PVDC coating to get more barrier properties since it has only average gas barrier properties.
PVC
PVC film is often used in a stretch wrap for pallets and industrial wrap (although in very small quantities). It is also used in some liners and bags, shrink wrap, labels, I.V. bags, blood bags, and adhesive labels. It is also exclusively used for packaging fresh red meats.
The film can be passed through by enough oxygen or can be said that it is semipermeable to keep the meat fresh and retain its bright red color. It is also puncture resistant and a good barrier to grease, and oil has excellent clarity and good cling.
PET
PET films are found in non-packaging and non-food applications such as X-ray films, photographic films, video recording, and magnetic audio film. Is also widely used in overheads and inkjet films, solar control films, luggage tags, business cards, and other general laminates.
However, its main packaging uses are in metal packaging, such as pretzels and potato chips, microwave packaging, medical and brick packaging. It can also be found in cigarette packs, tobacco packs, and labels.
Because of their good mechanical properties, they are used in these and other applications. It has stiffness and toughness. Compared to other resins, PET can withstand higher processing temperatures. It has clear or pigmented visuals, which is valuable in certain applications.
Several other resins are used in packages to impart special properties (those resins are used in small quantities). LDPE and LLDPE blends are used in several applications, such as heavy-duty shipping sacks, greenhouse films, and silage film production.
Make Your Super Silage Bale Wrapping By Using Silage Film
Poorly wrapped silage bales that cause silage spoiling and film torn during wrapping; these problems are familiar. For any farmer and contractor, these occurrences are a nightmare because they can increase time expenditure and costs, workloads, and poor feed quality.
Silage wrap can work wonders when used for super bale wrapping and storing. It ensures the freshness of the bales and can withstand even through the harshest of environments. So if you never tried using it before, it is about time you do.
