Sealable Antifog PET Lidding Films

TLID-AF is a transparent, anti-fog, heat-sealable, peelable BOPET lidding film. Its sealing side has an excellent cold anti-fog effect, which keeps the lid crystal clear under refrigeration. It seals at low temperatures and is microwaveable. It can extend the shelf life of fresh salads and vegetables by 4–5 days. It is used for:

- chilled and frozen foods

- fresh-cut fruits and vegetables, and salads

- ready-to-eat meals and pasta

- bakery items

- dairy

- fresh meat and salami

Anti-fog lidding film has a special treatment that stops water vapour from condensing into tiny droplets on the inside of the lid. Instead, moisture spreads into an invisible, transparent layer. The lid stays clear, so shoppers can see the product instead of a foggy, misted-up pack.

Fresh and cooked foods release moisture. When a sealed pack is refrigerated, that moisture condenses on the cooler inner surface of the lid as small droplets. The droplets scatter light, making the lid look cloudy. Fogging hides the product, looks unappealing, and can make shoppers think the food is old or spoiled.

Cold anti-fog means the film prevents fogging at refrigeration and chilled storage temperatures, where most fresh and prepared foods are displayed and sold. TLID-AF's anti-fog effect is on the sealing side, the side facing the product, so the lid stays clear throughout cold-chain storage and retail display.

TLID-AF is available in 30 microns and 41 microns.

- The 30 micron grade suits cups, punnets and high-volume fresh produce packs.

- The 41 micron grade adds stiffness and puncture resistance for larger trays, meat packs and premium presentation.

TLID-AF keeps the lid clear even when products are cold and humid. Shoppers can see the true colour, freshness and texture of salads, fruits, vegetables, meat and meals. A clear, droplet-free pack looks fresher and more premium, which helps sales and reduces rejected packs in retail.

TLID-AF helps extend the shelf life of fresh salads and vegetables by 4–5 days. Without anti-fog, condensation droplets collect and drip back onto the produce, creating wet spots that speed up wilting, browning and microbial spoilage. By spreading moisture evenly and preventing droplets, TLID-AF helps keep produce drier, crisper and fresher for longer.

No. The anti-fog effect works at the lid surface, stopping condensation from forming visible droplets. It helps keep the product fresh and attractive without changing its taste or composition.

Yes. TLID-AF is designed for a lasting cold anti-fog effect through refrigerated storage, cold-chain transport and chilled retail display. Actual performance depends on the product's moisture level, temperature swings and storage conditions, so we recommend a trial on your product.

TLID-AF seals to PP, HIPS, PET (including APET and RPET), PVC and LDPE trays, punnets and cups. This lets fresh produce, meat and ready-meal packers use one anti-fog lidding film across different container types.

Low-temperature sealing has three benefits:

- Line efficiency: faster cycles and lower energy use.

- Container protection: thin PET and PVC punnets and trays are less likely to distort.

- Produce protection: minimal heat reaches delicate fresh produce, salad leaves and chilled foods, which helps preserve their freshness.

Yes. TLID-AF is microwaveable, so it suits ready-to-eat meals, pasta and prepared foods that consumers reheat in the pack. Heating instructions, such as piercing or partly peeling the lid, should be validated on the final pack. The container must also be microwave-safe.

Yes. TLID-AF forms a secure, leak-resistant seal that peels cleanly by hand. That suits grab-and-go salads, fruit cups and ready meals.

The Application of TLID - AF are-

Fresh produce - Fresh-cut vegetables, fruits, salads, prepared fruits

Chilled and frozen foods - Refrigerated and frozen food packs

Ready-to-eat - Ready meals, pasta

Bakery - Cakes, pastries, sandwiches, bakery items

Dairy - Yoghurt, butter

Meat - Fresh meat, salami, cold cuts

Yes. Fresh-cut vegetables and salads are a key TLID-AF application. They have high moisture content and fog lids quickly under refrigeration. TLID-AF keeps the lid clear, shows off the fresh colour of leaves and vegetables, and helps extend shelf life by 4–5 days by limiting droplets on the produce.

Yes. Cut fruit, fruit bowls, fruit salads and prepared fruit cups release juice and moisture that cause fogging. TLID-AF keeps the lid clear so the bright colours of the fruit stay visible, supporting impulse purchases in supermarkets, cafés and convenience stores.

Yes. TLID-AF can be used for frozen food trays and packs. It helps keep lids clear when products move between frozen storage, chilled display and room temperature, where condensation often forms. Validate performance through your full freeze and thaw cycle.

Yes. Chilled ready meals, pasta, rice bowls and prepared foods fog heavily when sealed warm and then refrigerated. TLID-AF keeps the meal visible on the shelf, and because it is microwaveable, consumers can reheat the meal in the pack.

No. TLID-AF is designed for chilled, frozen and microwaveable applications, not retort sterilization. For retort products, use a retort-grade lidding film such as LRT.

TLID-AF is designed for direct food contact, including fresh produce and meat. Compliance certificates and migration reports for regulations such as FSSAI, US FDA and EU food-contact rules are available on request for your target market.

Yes. We provide TLID-AF samples in 30 and 41 microns for sealing and anti-fog trials on your products, containers and cold-chain conditions. Share your machine model, tray size and monthly volume for a tailored quote.

PSF (AF) is a 25 micron sealable, peelable, anti-fog PET lidding film made for fresh produce packaging. It is recyclable in mainstream recycling streams together with PET trays. It can extend the shelf life of fresh salads and vegetables by 4–5 days. It is used to lid PET trays and punnets for:

- vegetables and fresh herbs

- berries and fruits

- salads

- mushrooms

PSF (AF) is available in 25 microns. This thin, lightweight gauge keeps packaging material to a minimum while still giving a secure, peelable seal on fresh produce trays. It suits brands aiming to reduce plastic weight per pack.

PSF (AF) forms a secure seal on the tray flange that protects produce during handling, transport and retail display. Consumers can peel it off cleanly by hand without tools or tearing.

PSF (AF) combines three features in one film:

- an anti-fog effect for clear visibility of fresh produce

- recyclability together with PET trays in mainstream recycling

- a thin 25 micron gauge for lower material use

 This makes it a strong fit for retailers and brands with sustainability targets in fresh produce.

Yes. PSF (AF) is recyclable in mainstream recycling streams together with PET trays. Because both the lid and the tray are PET, the whole pack can go into the PET recycling stream. Consumers don't need to separate materials, and recyclers don't face the contamination caused by mixed-material lids.

PSF (AF) supports sustainability goals in three ways:

- Recyclability: it is recyclable with PET trays in mainstream streams.

- Material reduction: its 25 micron gauge uses less material per pack.

- Less food waste: extending produce shelf life by 4–5 days means less food thrown away.

 This helps brands and retailers meet packaging sustainability commitments and Extended Producer Responsibility (EPR) goals.

PSF (AF) helps extend the shelf life of fresh salads and vegetables by 4–5 days. By preventing droplets from forming and dripping onto produce, it limits wet spots that cause wilting, browning, sliminess and mould. Produce stays fresher and more saleable for longer, which reduces waste at retail and at home.

PSF (AF) applications are -

Vegetables | Cherry tomatoes, baby corn, cut vegetables, green beans, broccoli florets |

| Herbs | Coriander, mint, basil, microgreens |

| Berries | Strawberries, blueberries, raspberries, blackberries |

| Salads | Leafy greens, mixed salads, salad bowls |

| Fruits | Cut fruits, grapes, fruit punnets |

| Mushrooms | Button, oyster and exotic mushrooms |

Yes. Salads are a key PSF (AF) application. Leafy greens have high moisture content and fog lids quickly. PSF (AF) keeps the lid clear, shows off fresh green colour, and helps extend shelf life by 4–5 days by limiting droplets on the leaves.

Yes. Strawberries, blueberries, raspberries and blackberries are delicate and prone to mould when moisture collects. PSF (AF) keeps punnets clear and reduces droplet formation, helping berries look fresh and last longer on the shelf. The peelable lid gives easy access for consumers.

Yes. Mushrooms release a lot of moisture and quickly turn slimy or discoloured when condensation collects. PSF (AF)'s anti-fog effect keeps the pack clear and helps reduce moisture damage, so mushrooms stay fresh and appealing for longer.

Yes. Fresh herbs such as coriander, mint, basil, parsley and microgreens are highly perishable and moisture-sensitive. PSF (AF) keeps herb punnets clear and helps limit the wet conditions that cause wilting and decay.

Yes. PSF (AF) lids PET trays and punnets for cherry tomatoes, cut vegetables, baby vegetables, grapes, cut fruit and mixed fruit packs. It gives clear product visibility, a secure seal and longer freshness in chilled retail.

PSF (AF) is designed for sealing onto PET trays and punnets, including APET and RPET. This PET-on-PET combination is what makes the pack recyclable in mainstream PET recycling streams.

Yes. PSF (AF) runs on manual, semi-automatic and fully automatic tray sealers used in fresh produce packhouses. The best sealing temperature, dwell time and pressure should be set through a trial on your line and trays.

PSF (AF) is designed for direct food contact with fresh produce. Compliance certificates and migration reports for regulations such as FSSAI, US FDA and EU food-contact rules are available on request for your target market.

Yes. We provide PSF (AF) samples for sealing, anti-fog and shelf-life trials on your produce and PET trays. Share your tray size, machine model and monthly volume for a tailored quote.

PSF (AF) combines:

- a clean, easy peel

It is a sustainable, high-performance lidding choice for vegetables, herbs, berries, salads, fruits and mushrooms.

Here is the FAQ set for HSF-1, in the same format as the earlier product pages. Because HSF-1 is lock-seal (non-peelable), I've added questions on how consumers open the pack and how it compares with peelable lids, since buyers often search for that.
